LF-Plumbing Fittings and Flex PVC

[GreenSpottedPuffer]

I don't know too much about pricing, so for example, are these decent prices:

All Sch40

2" Gate Valve $18.45
2" Bulkhead $13.50
2" Unions $14.35
Black PVC Flex $17.62 (1.5" and 10' length)

Just a few examples of their prices. Wondering if this is pretty competitive?

Thanks!
