There are a number of reasons why little boutiques often dont get all the Tano bags that they order.
If their credit gets refused by Tano's factor, or their credit card is declined, they go on credit hold. Then, if the payment isnt made within a certain time, the merchandise gets bounced back into Tano's stock and re-allocated to another retailer.
Also, Tano gets way oversold on many items. When merchandise comes in, if there aren't enough units to fill all the orders, they get allocated to the biggest and best customers first. Therefore it can be risky when placing pre orders, etc, with these little boutiques. If they have something in stock that you want, that's one thing, but if you are going to wait for them to get something specific in to see it IRL, or if you place a pre order, you could wind up disappointed.
