Query: Unreliable Store

They advertised an incredible special on a dozen roses for Valentine's day. I placed an order more than a week before the date. Two days before Valentine's Day I receive an email saying order is being refunded. They did refund me my money, but the amount the refunded me was incorrect the first time. They corrected this mistake so I got all my money back. But the left me in the lurch for Valentine's Day.I would not recommend using them.
