Yes I use Wright's and I always buy at Create for less. It is the cheapest I have found online. I have watched ebay but never found any on there. I just use an Elmer's glue stick to put mine on the acrylic template. My assistant does these by 3 to 5 dozen of each size at a time and it works well for us.
There is a cheaper site that I have used but you have to wait a month to get them and you have to buy in bulk. Unless you spend over $150 and then they will send them in a week. Otherwise they wait til they have enough to place a bulk order. I was not real happy with them. I had some stuff that they backordered and they never told me I wasn't getting it til I contacted them. I just stay with Createforless. I have had good service with them.
