Last year I bought invites, recipes cards, and the mini catalogs. Honestly, I didn't use the invites & recipe cards until after I had placed a supply order anyway, and they were definitely heavy to carry around.
I did ship them UPS to home, but it was after I had already shipped my surprise box, so it cost me more overall. This year I'm just getting the mini catalogs to mail out when I get home and I'll buy my surprise box the same day to ship it all together.
Also -- not sure what (if anything) we will get for the new Round Up campaign, but I also shipped that home in my surprise box last year as well. That little heart stone did get heavy as well!
