Make a registry.. make it of big ticket items, (brand new kitchen maid 6qt mixer- 4-500$)
New sets of Pots and Pans (higher end stuff)
stuff like this that makes people think they are HELPING you to ultimately purchase these items... and would rather get you a gift card. (Your likely not gonna get cash, in my humble experience) You are gonna get gift cards... lots of gift cards.
Also, if they DO buy you bit ticket items.. No ones saying you cant unload them. I wont tell.
im my experience, they dont want to "help" pay for your honeymoon.. but this is just my opinion.
Remember gift giving is typically left up to the woman, and they want to buy stuff because woman are gatherers, so you need to play into that somehow.
When we got married, even with a good sized registry, we got more gift cards than gifts, and that was 10 years ago.
