I've got a couple of large purchases coming up (thousands of dollars). I plan to use credit card for that - I have the money for it, but various credit cards have 1% to 5% cashback bonuses, and with big purchases this can add up to a substantial sum, so I want to use it. Basically, I'd want to purchase it with the card, get the rewards, then next month when the bill comes pay it off from savings (which means I don't care about rates, etc.)
Now the question is which card to use for it. So does anybody know a site that, given the nature of the purchase (i.e. travel, home improvement, grocery, electronics, etc.) and date, would tell me which card it is best to use - taking into account all the rotating categories, temporary offers, etc.? There are a lot of sites that allow to choose based on monthly spending, features of the card, etc. but most of them do not take into account rotating categories and one-time purchases at specific time.
