I would like to get about 12 Flip Stay Dry inserts. I know some websites (like Cottonbabies) have a discount when you buy several making them about $4 apiece. But is there anyway to get them even cheaper? Like a website that has the occasional % off everything on the website sale? Or does Cottonbabies ever have seconds on these? I am not in any rush so I can wait if you know of a place where they might go on sale. Thanks in advance!
