I bought two Disney cards yesterday through Raise using TCB when it was 10%, one for $250 and one for $100. The $100 was done later in the day after it looked like the $250 was not going to track, and the $100 tracked pretty quickly. The $250, plus a large GC purchase I made on Feb. 14 (when they last had 10%) never tracked. I made another small purchase this weekend when it was 2%, but with $5 TCB bonus cash, and that one tracked quickly. The TCB site mentions purchases over $1000 not being valid, but at least anecdotally I'd say any "larger" purchases seem to not track. I guess I'll just slowly chip away at the $4000 I need for May as good deals come up.
