The Lingerie Bar review for PreOrder Now Backorder WOD

I am looking for an pre-order app for my store and somebody suggested this app to me. It is easy to use and the support from Rasheem is wonderful! However there is no function to apply pre-order to all products or a group of products yet so with my store (more than 1000 products), I feel hard to click "enable pre-order" to each single product. Anyway, highly recommend if your store dont have too many products like mine.
