I figured that you were using SCH40... That's the fact... Keep on selling them like hotcakes... Pvc is sold in 10' lengths, so your paying more for shorter cut pieces. Notice the weight differences below, ABS is 7lbs, PVC SCH 40 is 15lbs, PVC SCH80 is 20lbs.

As far as the prices, the store in my town has SCH80 PVC way over ABS, it's a small town, what can I say... I'll be buying pipe from Grainger from now on...
The weight difference is huge and that's the key...
Here's the SCH80 PVC that holds its shape and has the best strength

The SCH80 fittings are what I used, big difference in the weight and price, they don't break as easy as the sch40 or less PVC. I haven't bought SCH 40 PVC in years because it cracks to easy. ABS lasts and is so much lighter
