I purchased (online) a pack of Clean Ones Premium Household Gloves from Glovesaver.com for $12.34, and I received an online confirmation and an email confirmation that the price was $12.34. Glovesaver.com then billed my credit card $21.51. When I complained to Glovesaver.com, they acknowledged their mistake and they said that they would credit back the difference ($9.17) to my credit card. Glovesaver.com never gave back the $9.17 despite my several phonecalls and emails to them during the next month. Finally, I had to dispute the charge with my credit card company by sending them all the paperwork, and my credit card company credited the $9.17 to my account.
