Q: eBay sometimes defaults to PayPal as your payment if you've used it before on eBay. It's sometimes easier to simply pay as a guest and then enter your card information. Sometimes, the eBay site will keep redirecting you to the screen where you pay via PayPal even if you request otherwise. If you're having this issue, try clearing your browser history as well as your cookies. This may clear up the issue. If you prefer not to use your PayPal account for eBay, do not link your eBay and PayPal account to begin with. If your PayPal is linked to your eBay account, this can sometimes result in PayPal being your default payment option. If you've already linked your PayPal and eBay account, try creating a different eBay account with a new email.
A: Pay as a guest if you've used PayPal before. Try clearing your browser's history. Do not link a PayPal and eBay account.

Q: This would be terrible if you are caught with cards in your lap as you are about to go out of cards, so this should keep people from cheating. Similarly, there could be a rule that says the person is "out" if they cheat. This is where they are still playing the game, but are ineligible to win, get an Uno, or make other players draw cards. They must forfeit any action cards in their hand upon being caught cheating.
A:
Come up with a house rule that makes you draw another full hand if you are caught cheating.
