Weddingbee boards

I've used this company: Paper Mart to buy a lot of different things.  Not gable boxes, though, but they do have them.  I've bought both for work and for my wedding stuff.  They've had really nice customer service, and stuff arrives quick, and it's been quite reasonably priced.  The catch is that the larger size gables (avail. in all sorts of colors) only seem to come in 100s.  (But they're less than $50!  A great deal!  Maybe you could sell your left overs on BeeClassifieds.)  They also have cute clear/frosted gables that come in 24s, but they are pricier.  I recommend checking them out.
