That's really odd.    
I buy vitamins on amazon, they charge about $7 with free add on shipping, they're sold out right now and the amazon sellers want $10 plus $7 shipping. I wonder why they're allowed to charge more for shipping a small item than you were.    
Idk how it's worth selling on amazon, either the prices are so high no one buys it, they're taking a hit, or their price is so close to amazon's people pick amazon for the fast shipping and customer service.     |
