Extra entries on the same card

  • Hand-write the matching code (e.g. “MULTIPLE-60X”) on the bottom left-hand side of the front of the envelope, corresponding to the sponsor-announced entry multiplier active on the postmark date.

    Multiplies the mail-in's entries by the announced multiplier (5X up to 100X) for that specified time period.

    Risk: The postmark date must correspond to the announced multiplier/bonus date or the mail entry is void.

    Show the rules' wording

    “must handwrite the words ("MULTIPLE-5X”, "MULTIPLE-10X”,... or “MULTIPLE-100X”) corresponding to the Sponsor announced entry multiplier opportunity offer) on the bottom left hand side of the front of the envelope if he/she would like to receive the multiple entries.”

  • Hand-write “Exclusive Bonus” or “Bundle Bonus” on the bottom left-hand side of the front of the envelope while that product offering is posted on the website.

    Adds 1,000 bonus entries for that mail-in.

    Show the rules' wording

    ““Exclusive” and “Bundle” product offerings: There may be bonus entries available for “Exclusive” and “Bundle” product offerings for any valid Sweepstakes purchase, or mail-in entries, during the Promotion Period. Each Participant completing a purchase of either an “Exclusive” or “Bundle” product offering will receive one thousand (1,000) bonus entries for each valid purchase submitted. During the time the “Exclusive” and “Bundle” product offerings are posted on the Website, mail-in entries must follow the aforementioned mail-in entry submission process and must handwrite the words "Exclusive” Bonus or “Bundle” Bonus on the bottom left-hand side of the front of the envelope if he/she would like to receive the one thousand (1,000) bonus entries.”

  • Hand-write “Checkout Speed Bonus” on the bottom left-hand side of the front of the envelope.

    Adds 2,000 bonus entries for that mail-in.

    Show the rules' wording

    “Checkout Order Speed: Participant that complete their on-line order within three (3) minutes from the start of their order will receive two thousand (2,000) bonus entries. During the Promotion Period, mail-in participants must follow the mail-in entry direction above and must handwrite the words "Checkout Speed Bonus" on the bottom left-hand side of the front of the envelope if he/she would like to receive the two thousand (2,000) bonus entries.”

  • Hand-write “Mega Bonus” on the bottom left-hand side of the front of the envelope.

    Adds 3,000 bonus entries for that mail-in.

    Risk: Limited to a maximum of two (2) “Mega Bonus” entries per participant during the Promotion Period. Only counts during the sponsor-announced Mega Bonus Period. The rules give no dates, so check ownbosssupplyco.com before writing "Mega Bonus".

    Show the rules' wording

    “Mega Bonus: Mail-in participants can earn a “Mega” bonus equivalent to 3,000 bonus entries for each “Mega” entry submitted up to a maximum of two (2) on all entries submitted during the Promotion Period.”

  • Hand-write “Boss Talk Bonus” on the bottom left-hand side of the front of the envelope.

    Adds 8,500 bonus entries for that mail-in.

    Risk: Limited to a maximum of two (2) “Boss Talk” Bonus entries per participant during the Promotion Period. Only counts during the sponsor-announced Boss Talk Bonus Period. The rules give no dates, so check ownbosssupplyco.com before writing "Boss Talk Bonus".

    Show the rules' wording

    “Boss Talk Bonus: Mail-in participants can earn a “Boss Talk” bonus equivalent to 8,500 bonus entries for each “Boss Talk” entry submitted up to a maximum of two (2) on all entries submitted during the Promotion Period.”

  • Hand-write “Loyalty Bonus” on the bottom left-hand side of the front of the envelope.

    Adds 500 bonus entries for that mail-in.

    Risk: Only counts during the sponsor-announced Loyalty Bonus Period. The rules give no dates, so check ownbosssupplyco.com before writing "Loyalty Bonus".

    Show the rules' wording

    “Loyalty Bonus: Mail-in participants can earn a “Loyalty” bonus equivalent to 500 bonus entries for each “Loyalty” entry submitted during the Promotion Period. During the Loyalty Bonus Period, mail-in entries must follow the aforementioned mail-in entry submission process and must handwrite the words "Loyalty Bonus" on the bottom left-hand side of the front of the envelope if he/she would like to participate in the Loyalty bonus offering.”

  • Hand-write “OB46” Sweepstakes on the bottom left-hand side of the front of the envelope (in addition to the required “OB46 1983 Chevrolet C10 Truck” Sweepstakes entry text on the card itself).

    The same mail-in also earns the equivalent entries in the concurrently-running main “OB46” (F-450 + Cat machines) sweepstakes — one card, two sweepstakes.

    Risk: Only valid while the two sweepstakes are running concurrently; the OB46-C10 Promotion Period itself ends September 20, 2026 even though its own postmark window runs through September 21 — it is unclear whether a September 21 postmark still counts as "concurrent" for this cross-entry.

    Show the rules' wording

    “For mail entries that want to enter the “OB46 1983 Chevrolet C10 Truck” Sweepstakes, and also the “OB46” Sweepstakes (during the time where the two Sweepstakes are running concurrently), can write “OB46” Sweepstakes on the bottom left-hand side of the front of the envelope to receive the same entries corresponding to both Sweepstakes.”

Oddities3

  • Section III says there are “four (4) entry methods” but then lists five (purchase online, purchase at a marketing event, subscription, loyalty program, and mail) — a drafting/count error in the official rules.

    Show the rules' wording· III. How to Enter (header)

    “enter the Sweepstakes via any of the following four (4) entry methods: 1) Purchase Sponsor Merchandise:”

  • The administrator's name is rendered three different ways across the rules: “Compliance Sweepstakes Services, LLC” (Eligibility), “Compliance Sweepstake Services” singular (Winner Selection), and “Compliance Sweepstakes Services” with no LLC (Administrator section).

    “Compliance Sweepstakes Services, LLC (collectively, the “Released Parties”)”

  • Michigan residents are excluded even though Michigan is a contiguous mainland state (unlike Hawaii/Alaska, which are the more typical non-contiguous exclusions) — no reason is given in the rules.

    Show the rules' wording· II. Eligibility

    “Void in Hawaii, Alaska, Michigan, Puerto Rico, the U.S. Virgin Islands, Guam, U.S. Military installations in foreign countries, and where prohibited, taxed, or restricted by law, regulation or ordinance.”
