Hi Helen. The answer to your question is both Yes…and No. Some items will appear to be sold out but that is usually only temporary. People add and drop stuff continuously throughout the sale. It is literally minute by minute. I tend to mark my favorites, then hit refresh about 100 times a minute lol. And you may not have any luck one day and then the next day, 4 things you wanted are back in stock! You just have to keep trying. And don’t get frustrated when you first get started. Chances are, anything and everything you want will be available at some point through the sale.
Also, there is typically a forum topic on it and some people will “drop” an item for you if you are struggling to get something you want. My BFF is not a select member so she has later access than I do. However, because she HATES playing around with the sales, I usually grab the things she wants (especially hard to get items) and then “drop” them for her when she is available.
So there are multiple ways to score an item. Hope you have fun with it and get all the goodies you want!
