I go in for something, and if Rob isn't with me, walk out with a ton of things I don't need and hadn't planned on getting. When we have our own house and have to do 100% of the shopping, we'll be looking at circulars and whatnot, clipping coupons for stuff we need, etc. But who knows how long that'll last!! He only wants to grocery shop 1x a month, and if I go every week, we'll spend tons on stuff we don't need because I'm the shopper who goes in for 2 things and walks out with 20!
