I used to buy all my vitamins and collagen powder from Vitacost(Kroger owned). It was sold to iHerb holdings.

I received an email for a 30% off sale on everything. I ordered a bunch of things, but after checking out I discovered that 30% had a maximum amount of $10. My bad, I didn't notice that under the graphic which took up 3/4 of the email was a notice that said the maximum discount was $10, very unlike Vitacost, which had no limit. A lesson to look for the fine print, especially when a business changes hands.
