Wow, warmpancakes made a well thought out post, that explained a lot of things very clearly. Well done.
I've never seen a credit card that compounds interest daily. Charges interest monthly on average daily balance, yes, charges interest daily, no. See "people who use their card for everything to earn rewards, pay in full each month, and don't pay interest."
If they're simply calculating interest on the balance at EOM, you're kinda sorta paying more interest by paying weekly, as you lose the use of your weekly payments for 1-3 weeks each month, with no compensation vs. paying 4x as much once at the end of the month. It's not literally costing you more, but it's tying up money you could use elsewhere for 0 gain.
But anyway... screw that for that cost, especially at that rate, and even at several points lower. I'd want it in 2 boxes anyway. You're not rolling that big ***** around all the time anyway, who cares if you spend an extra 5 minutes getting 2 of them lined up perfectly? Then they're easier to move, easier to sell (one or both) and dor that matter, you could probably get a better deal on them. I can tell you from experience with patience you can order a Snap On box, brand new, for <50% of list... and from reading on here it seems there's even better (percentagewise) deals to be made on the huge, astronomically expensive boxes because they're not big movers.
