We don't have a set limit, but like some others we like to make sure the kids have an equal amount to open. This year they are getting a cubby house with kitchen etc inside & I'm selfish I want the credit for it so that's coming from us & the other things are from Santa. I'd say I've spent about $150 on Zander (aside from the cubby house) and will be close to that for Juliette when I'm done too.
