I am burning money by buying cake boxes from Michaels and Walmart..where would ya'll recommend to buy them in bulk from?
You can also try www.webstaurant.com. There is a shipping fee but they have really reasonable pricing.
PaperMart sells boxes in cases of 100, and also charges for shipping, but my shipments get to me within 2 days due to their using FedEx Ground. We're both located in California, which has a lot to do with the fast turn-around.
Catering supply stores usually sell boxes and circles. Cheapest places are bakery supply or paper supply stores that sell by the bundle.
