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

It's really hard for me to buy any of TS4 packs at full price. The ones I do have were either gifted to me or I got on sale. What's funny is that I actually really want almost all of the Stuff Packs, but I don't want to pay for them at full price. However, if they all went on sale, I would actually pull the trigger on all of them at once. Now, without the sales, I don't buy any of them...

But you know, all of the people who buy the packs at full price, despite the many sales offered to them at later dates, keep EA from starting at a lower price, I guess.
