Wishing well - money or vouchers?!

[OhPuddleducks]

Brides and/or brides-to-be, please can you help. I'm off to a wedding with a wishing well for gifts. What would you be hoping for - money (as in a stack of twenties or similar) or a gift voucher for John Lewis or Mr and Mrs Smith or somewhere in that vein? this is the first one I've had where the well isn't "for" something, eg honeymoon, so I feel a bit unsure what would be best.

I really wouldn't mind either way (not very helpful!) John Lewis is a pretty good bet as there's bound to be something they'd like in there.

Are they going on honeymoon?

The last wedding I went to, I knew they were going to Florida so I gave them $ ...I was the only one out of 100 guests who gave currency and they loved it.
