if you dont like cash, do as mentioned - gift vouchers. we got heaps for target and i bought a knife set i would never have afforded by ourselves and a booster seat for our 2 year old....

personally it wasnt about how much people gave us, we were just happy they showed. its just we had all the essentials and didnt want people to waste money on goods we didnt need. plus the wishing well makes it private and nobody else knows what you did or didnt give. a friend who was strapped for cash and gave us $50. we felt so guilty they had done that so we took them out for a buffet dinner a couple of weeks later.
