Credit Guaranteed Packages

Packages with Credit Guarantees automatically give you a credit if the package does not turn a profit—the sum of betting all individual picks. THESE ARE NOT PARLAYS UNLESS OTHERWISE CLEARLY STATED. If a credit guaranteed package does not profit, a credit for its full purchase price is automatically issued after picks are graded and verified.

For example, if you purchase a $39.95 package that doesn’t profit, you’ll get a $39.95 credit towards any future purchase(s) on our site. Credits are usually issued within hours of a game’s conclusion, so please allow a few hours for final verification.

To use your credits, log in to your account and add another package or pass to your cart. Credits will automatically reduce what you owe. Any remaining balance will be settled through our payment system, with any leftover credits available future purchases. Credits do not expire.
