Sandal shopping

I want to get a pair of very comfortable black sandals for mom to replace the worn-out pair I left for her a year ago. I had my eyes set on this pair of black sandals at Easy Spirit, and was waiting for them to go on sale. Yesterday I saw them on sale online, rushed to the store, but her size was out. Then I tried to purchase today and they are out online, too. I shouldn't have hesitated, indecisiveness sometimes cost more trouble and time.
