Drugstore.com send me an email advertising 20% off entire order. I clicked through and shopped. The 20% discount was reflected at checkout. However, when I got the invoice for the order, it showed only a $5 discount!! They ripped me off to the tune of $17. I immediately tried to cancel, but they said they were"unable" to do so. Now I have to hassle with Paypal for a refund. I will never shop with these thieves again. read full review »
