"I have had the Worst online buying experience ever with Allheart.com. I had a coupon good for $10 off, & decided to go through Allheart.com since it was a little less expensive with the coupon. Went online & ordered a Littman 3 Stethoscope & checked out. No word from them & then I got an e-mail 3-days later stating I could not use the coupon any longer & that the new amount was more. Not sure why the online checkout allowed me to use the coupon if it was invalid in the first place. I simply replied to the e-mail to cancel the order & placed another order through another online retailer. I figured this was ok since they are not supposed to bill you credit card till the item ships. Well, they went off & charged the new, unauthorized, amount to my debit card. I called & they said they would refund my money, it should be in my bank with in 72 hours, still no refund after a week & my bank has no record of the amount wanting to be placed back in my account. This is great since it caused additional fees for being overdrawn. Thanks a lot Allheart.. Buyer beware"
