Not sure how this is possible. It has happened twice, back to back with different variants of an item. I'm selling a single tee shirt with different sizes. Here are the config options i have checked:
Sales Tax, VAT
Let Buyers edit quantity in cart
Variants having different price/weight/stock/SKU
and then on the proceeding page i have my options broken down like this, repeated for the different sizes of shirts:
everything worked like clockwork. i get emails when stock gets down to 5 left and then an email every time it goes down after that. once it gets to 0, the cart no longer allows the user to buy the item and gives them a popup saying so.
but today, with 0 items of any of my sizes left in stock, i see i sold 2 more tee shirts! and i get emails saying -1 Medium left in stock; and -1 XL left in stock.
how is this possible? i went back to the cart and tried to do it myself but i get the pop up. the only thing i can think of is these 2 people placed their item in the cart when it was still in stock, but didnt buy it. left the site. came back today, clicked on their View Cart link and saw the item was still in there. clicked on buy and continued to purchase. is that possible? not sure. its the only thing i can think of.
any help would be appreciated. i've enjoyed e-junkie so far. no other issues. pretty smooth integration.
