Just did my card and my wife's card on 4/1 and today at our local Target in MA. Did 2500 on each card each day, so we're done for the month. My "innovations" this month: 1) using totally not-round-numbers for the CC loads and 2) loading GC's.
I had about 3 $500 GCs I had bought to finish the Freedom Q1, plus I went out and bought 5 $200 GCs from Staples to get 5points/$1. The advantage I see of mixing GCs with CCs for loading is that there's less chance of getting the charge denied by the CC due to fraud protection alerts. The amounts are lower and it's fewer CC charges. The downside, of course, is that it's more swiping at the Target register -- so if they're busy or annoyed, not good, but that wasn't an issue for me. Also, there are the GC fees, but I think it's a reasonable tradeoff. Just my two cents.
Wishing everyone a chag kasher v'sameach!
