Please pardon my mistake!
Trying to differentiate between the costumes which are Rental and which are Retail becomes an issue on the web because the two words are very similar at a glance. At the same time, if one refers to products FOR SALE, causal web surfers may believe they are ON SALE at reduced prices. Therefore, the decision was made to use the terms BUY and RENT on new and revised pages.
The newly created page to show all the adult sized retail costumes was listed as "Buy Adult Costumes". Luckily, a friend pointed out the error and it has been changed.
