imo, ebay is the best place for pollen. the local health food stores usually sell it for about $25-30 lb, sometimes the discount supplement places (like super-supplements) have it for cheaper. you can buy a pound of pesticide free bee pollen on ebay for less than $ 15 lb shipped, probably cheaper if you looked at enough listings. i have seen 10 lb bags on ebay for as little as $45. sometimes walgreens has it on sale. i use it in gutload, but i do not dust with it. i think it is just better suited to gutloading.
