Hi, I thought I'd share the message I've seen a couple times when I tried to collect an item from Target, in this case a navy lace top that I own already. The message says:

It is only possible to collect items from the clothing, footwear and accessories categories at Target

I'm not sure why it says that, since it is an item of clothing and is from a clothing category(Women's). Just thought I'd share in case someone else has the same problem or a solution.
