1. Some credit cards don't accept $1 charges

would be really stupid of them not to since EVERY single billing company I know of attemps a $1 charge to validate the card.
I would most definitely hunt down these cards so I knew which to avoid like the plague.

This is actually changing since processors are now charging extra fees when auths are not captured or voided. The industry is changing to $0 auths which only verify basic information like billing address and CVV. This is still facing a similar issue though with credit card issuers declining $0 auths. It may change in the near future though since this is the way payments are trending.
