Sims sales make me regret day 1 buys...but why not just make them cheaper anyway?

At this point I just wait for sales there never to long after release at least with expansions I got University half off less than 2 weeks after release seeing as I was in no rush only cared for the bikes it was no issue. But really at this point besides Generations I cant imagine paying full price for a expansion that feels half complete and that has been all of them besides Get Together.
