To the op: they had more merch stands than you thought necessary? I don't even understand that. (And I may have paraphrased your original statement.) With a theatre as large as that, I think its actually rather nice to make it easier for their customers.
As far as personally? I wait on two things: to make sure I LOVE the show, then to see if there is anything I love on the table. More often than not, I do not purchase anything. Heck, I don't even save Playbills.
I probably have more baseball hats than anything else, however.
Even my kids have different takes: when we go to NY (just returned from a 4 show mini-vaca), they are only permitted to pick something from ONE show we see. My daughter wants everything. My son, not so much -- in fact he ended up with a tshirt from John Pizzaria, go figure! (In all fairness, he loves it there and he does want to be a chef.)
This year, I think I bought two things, a hat from Peter and the Starcatcher and a tee from Once. I probably go to the theater close to 30 times a year, and I think that's all I got.
If we're not having fun, then why are we doing it?
