BUY
Whether you need protective clothing, beekeeping tools, extractors, hive boxes, or bees themselves, you need to do your research to find the best value.  Oh ya, and make sure you're getting good quality because who wants to be stung repeatedly through a cheap, thin bee suit?
We're not going to pass judgement on where to get the best products at the best price, just give you places to start.  First, if you have local beekeeping supply stores, start there.  Even if you pay a little more for the products you will likely get all kinds of free, local advice... and that has value!  Talk to your mentor and other local beekeepers.  Here are just a few of the many online places to start.  Happy shopping!
