From a WL I sent a charger. When I tried to send a collection item, I got a message that I could only send one gift. I didn't think I did, but I couldn't say for sure.
Forward to yesterday. After gift counter reset, I sent someone a collection item first, then a charger, both from WL.
Next person, I sent a charger from WL. When I tried to send a collection item...you guessed it...couldn't do it!
