[Plugin: WP e-Commerce] Stock not deducted

products a setting as below
name product a
price 0, sale price 0

i tick on
– category “peyek”
– do not include tax
– I have a limited number of this item in stock. If the stock runs out, this product will not be available on the shop unless you untick this box or add more stock. (i put 2 in the box)
– Disregard Shipping for this product

i used variation of “keping / pieces”
variation 10, stock 0, price 3
variation 25, stock 0, price 6
variation 50, stock 2, price 12

when user go to products page, default variation is 50 (which is correct), price shown is MYR 3( which is incorrect, howver when you click add to card it goes well with myr 12)

go to check out, at the quantity, is now 1, update it to 2, update it to 3 in sequence, all the numbers are update, bare in mind my quantity is 2 actually.

after complete the check out, product quantity should be deducted, however, it still remains 2. and user still can “buy” the product.

i’ve tested with :
1. mozilla 3.5.6
2. ie 8
3. safari 4.0.3 (531.9.1)
