Hey Chelle.
-If only one product is on sale we want the sale linked directly to the kit.
-If you have your entire store on sale you can link to your designer page.
-If you have a buy my store product you would link only to that page
-A grab bag is still kind of a sale. You get a bunch of product for a great deal. So sure post them in there. Just make sure you put the date the sale ends. If you are always going to have that grab bag available I would say put it in the bundled sticky thread.
-I don't see a problem with linking to the entire scrap matters store as long as it is a store wide sale.
Clear ad mud??
Basically we don't want scrappers to have to go on a hunt to find the product(s) for sale.
