I inputted all of my wedding purchases on an Excel Spreadsheet with links if applicable. By referencing my Excel Spreadsheet (or you can bookmark your wedding purchases), I was able to save an additional $73.65 on my wedding dress.
How? From time of purchase of my dress, I occasionally checked up on my dress online and saw that my dress dropped in price. I contacted customer service within the price adjustment time frame and was approved.
Be sure to check your store policy for any items you purchased for your wedding and if price adjustments are possible. If so, you could save some money, just a tip that worked for me.
