When you get home, make a list of the items you wanted, but weren't able to find at a bargain price. Now, it is time to get online. The first place to go is the clearance or sale tab. Peruse through this area to see what kind of deal you get. Often, you can score some great finds in the online clearance/sale section, especially with plus-size retailers that only operate online.
Make a list of your specific measurements and how fabrics generally drape over your curves. Cross-reference with it before you make a purchase. This will enable you to make informed choices when purchasing clearance items, which are often nonrefundable.
