Hey Dan, when you apply for the same card several times in a year, do you spend any money on them after you get the signup bonus? I can't imagine how I would manage having several cards and using them all. As it is now I have maybe 6 different credit cards from 4 banks, but only use one or two in any given month.
If you don't use them after getting the bonus (for example the continental onepass card gives the bonus after first purchase), have they ever been suspicious of how many accounts you open and close with hardly any usage?
