I don't think it's tacky either - as you said if it's done in a way that leaves the option open for people to buy a gift if they would like to. I know some "older" people have issues with it, my MIL doesn't like it but thats just her!

We also had a wine cellar shower for our engagement party - we had everything for the house - having lived in it for 5 years and so we still now have some fab bottles of wine in our cellar! We also got bits and peices like openers, stoppers etc.

We had a registry with Flight Centre for our honeymoon which we took 2 1/2 years after our wedding but the money there paid for our flights!

Have fun with it and here is a recent poem we were given for a wedding this weekend- the groom wrote it

Your presence at our wedding, is present enough, Dont worry what to buy us, we've plenty of stuff. We have a new house, that we've filled to the brim, crockery and furniture will no longer fit in, If its a gift you'd like to give us, On our special day, The gift of money for our honeymoon, would help us fly away. So a wishing well at the reception, we've decided to have, Place this envelope in it - We'd be grateful and glad!!
Attached to a little envelope!
