Wow, thanks for the warm welcome!
And thanks for the DISchurners invite!
DH has sold on eBay in the past but hasn't done so in, oh maybe 5 years? Otherwise no side gigs of any stripe. Uh, if needed in order to qualify for a business card I could probably get him to sell a few items here or there.
We're happy to open and use as many cards as needed for any sign up bonus. For example, get/use CC1 for 3 months to get bonus X, then stop using CC1 and get/use CC2 for four months to get bonus Y, stop using CC2 and get/use CC3 for 2 months for bonus Z. More than happy to go this route, and could manage even attempting to do two CCs at the same time as long as we'd have a good chance at making the minimum spend for the bonus.
What we are
less looking to do is using multiple cards on a daily basis for different categories. For example, CC1 for gas (except for BP stations where we use CC2) and CC3 is for restaurants (except Starbucks where we use CC4) and CC5 is grocery stores except Target because we use CC6 and so on. That sort of thing DH would never get on board with and honestly I'd also find to be too taxing.
