Buying at the last minute is a bad idea with indieroyale. Prices get higher and higher on that one the longer you wait.
They're only around 1 USD more on the last day vs. the first day. Waiting is fine, it has a very small net difference. I guess you might have to skip an extra candy bar, but that's the scale of the sum we're talking about here.
Doh, stupid work, I missed out. It was only a 7 cent difference over the last day though. I stalled because I really only wanted Unstoppable Gorg and it was basically only 50% off... I could probably snag that on a Steam sale one of these days.
