Our family recently made a purchase from drugstore.com online. No problems with the actual purchase, but somehow we didn't unlick some box during electronic checkout and we were signed up for a $12 monthly recurring bill for a service called 'Complete Savings'. We didn't want anything from 'Complete Savings' and didn't even know they existed until a bill showed up on our credit card.
After a few minutes on the phone today with our bank and then finally Complete Savings the charges will supposedly be reversed and our 'account' with Complete Savings closed. I found it ironic how quickly and easily they removed the service. There was even an option on the primary phone menu to remove yourself. I surmise they get a LOT of requests for removal. I suggest you not do business with either completesavings.com or drugstore.com.
Some of you may say I should just read the terms of service and be more careful when shopping online, but I'm calling bullsh*t on that. One should not have to be concerned with accidentally being charged for extraneous external services. If your company chooses not to act in a respectful manner, so be it, but don't complain when I tell others not to shop at your company. I only want to watch Ferengi on TV, not interact with them in real life.
If you google 'complete savings scam' you will see other companies have been caught in this scam of tricking their own customers in a desperate attempt for more revenue.
