I just bought a few new hives and paid 8.55 for deeps, 6.95 for mediums, .85 (deep) and .82 (medium) each for frames, and 6.95 for migratory covers. For me, buying this stuff is actually cheaper than building from scratch. I can't buy the lumber at the rates the equipment suppliers do.
Migratory covers are much cheaper than telescoping covers. You can still cover them yourself with aluminum flashing if you want. The flashing is available at home centers and is fairly easy to work with.
Make sure you take shipping into account. Woodenware is heavy and sometimes it makes sense to pay a bit more for the product from a supplier that is closer.
Also, you can often get some decent discounts for buying quantity. Use this winter to find a bee club and put together a mass order. The savings can be substantial.
Package bees are the same story. Get a large order together and you will save money.
If you work hard and are careful, every hive will more than pay for itself by the second year.
I also use a tyvec suit instead of a bee suit. They cost about 6 dollars each and I typically can make one or two last for the entire season (might have to tape up a tear here and there). Actually, I can afford a bee suit but I still use the tyvec because it's disposable and I don't expose my household to bee venem by washing a suit.
