Where is the best and cheapest place online to buy cake and cupcake boxes online?

I'm losing money buy 5 here and there from amazon

thanks!

how many do you want to order at once?

Shipping can kill you, but even hobby lobby stocks some and you can use coupons. 

The nearest hobby lobby is 6 hours away :( shipping is the killer.. I want to have at least 10 of all sizes on hand. 

Check brpboxshop.com - shipping is included on all their prices, and they sell in lots of 10, 50 & 100! 

^^^^ The boxshop above is recommended by most and very flexible to stock the supply you are looking for. In large quantities of 1000+ I think there are a few cheaper sources.

Do you have a cash and carry place near you?  I know by me, I can buy from a cash and carry place for very cheap!  A box of 200 single cupcake holders for 28 bucks :) or a dozen holders, 100 of them for 61 bucks.  Otherwise, the boxshop is also a good site to use!
