while at a lfs today, a person was there selling liverock to the lfs from a tank he had just taken down. i watched as the clerk weighed it, and came up with a total of 85 pounds. nice purple rock, with some life to it. he gave the person selling it $42.50. thats .50 per pound. now i know he didnt have to sell it to them, but, is it just me, or is that taking advantage. this store sells it for close to eight dollars a pound. i dont know, but didnt seem right. is it just me.
