Usually I spend about $50 in total, I make their cake from scratch and decorate it anyway they want, I buy decorations at a party supply store ususally they've been discounted up to 80% off so that's not alot, I do make up little treat bags and I plan lots of games for them to do. LAst year I had free pizza coupons so I used that for both theboys party....I think with all the free things and stuff form the discount store I only spent $25 for each party....the kids are always asking when Alex and Kyle will be having their parties because I do fun games like dunking for apples, hot potatoe, decorate pumpkins, pumpkin bowling things like that....almost all of the stuff I already have because Alex's birthday is 3 days before Halloween and Kyles's is the same week as Thanksgiving.......
