Newbie question

I’m new to collecting Marvel Legends. Got into in because I wanted to get the full wave of GOTG 3 figures. I was looking for some advice on a situation I have going on.

I have Drax and Kraglin preordered through Target(with a gift card), but it’s clear to me that they are out and order-able through other places. It’s been about a month that I’ve had them on preorder. Should I just keep waiting for Target to send them to me? Does anyone know why Target is doing this if these figures are widely available elsewhere?
