I Do I Do Wedding Gowns

Review: Today, Saturday July 26th, 2014. I arrived at this shop with my daughter just before 5pm. The sales lady greeted us and said they are just about to close. I asked if it was ok for me to quickly look for a dress because I have a wedding to attend next Saturday. She said that's fine and pointed to a rackfull of dresses that were all on sale (50% ) off. I quickly tried on 2 dresses of the 3 I had picked. I loved the maroon dress, and please note all three dress had an orange sticker on the price tag with $99 written on all 3 dresses. The sales lady asked if all was well and I replied that I was so happy I found a dress that looks good on me at such short notice. She took the dress away and came back with a new blank orange sticker saying its not $99 but half of the original price of $450. I immediately voiced that this is so unfair, why she change it like that. I asked to see the Manager and she said she is the manager. I took pictures of the 2 dresses I had tried on and the price tags. I pleaded with the other sales lady who came round to see what was taking place. I felt so disheartened. I have shopped in this boutique before but never experienced such treatment. I just don't have time to go looking for another dress. I have a very busy schedule, as a Registered Nurse in a DC Hospital. Please help.Desired Settlement: I strongly think the business has an obligation to honor the price they put on an item. I honestly can afford a $450 outfit but its the principal behind this event.
