I think it really depends on if you are a vic/ vvic or not for the pre-order. How your store view you and your purchase history. Also some stores do work with resellers while others don’t. So all of these get taken into account whether you get the pre-ordered bags or not (regardless if you pre-paid or not). The speed of refund also depends on how the store view you as a client. If you are an important client, you can be sure your store will refund you quickly. If you buy a canvas bag, couple slg and few sunnies, every half year, then you will likely have to wait for your refund if you don’t get your pre-paid bag.
Now they will only take pre-order for leather and rtw. Each store is allocated x number of canvas bags in advance. The man’s manager will look at purchase history/ and purchase potential when allocating canvas bags. It’s just smart business on their end. Not so good for people who only buy few canvas things here and there.
