Query: Price went up! Used to be $27.99

I really love Enfamil, as its the only formula that my preemie daughter would except. I was sooooo excited to see that Amazon had the 38oz cans for only $27.99 each, so I ordered several so I wouldn't run out. The next time I went to purchase more, I noticed (after paying) that the price went up $3 per can. My local Sam's Club now sells the 38oz cans for about $1.50 LESS. I'm very disapointed in Amazon. Sam's has won my baby business.
