We had a wishing well at ours because I'd been previously married and still had all the presents from the first time around. And we really really didn't need anything. We got our cards separately in a pile, and people just dumped money in - so we didn't know how much they gave (nor did we care). The only people we know how much they gave was the IL's because they paid for the venue for us.

We still got some presents, which we never used (mostly photo frames) and I ended up giving them away to charity when we moved down to tassie.
