I was at the Jersey City Marshall's (Rt. 440) last night and saw several wedding items (I think from the Brides.com brand) for sale. There were place cards (I saw pink ones and blue ones), Save the Date kits, a "Bachelorette Party kit," etc. I have this stuff already, or I don't need it, so I didn't look very closely at what else was there.
I also got some thank you cards for $4 a pack. Not wedding-themed, but they had a variety of colors and patterns available. I think my shower is coming up soon so I figured I'd stock up.
