PROBLEM with putting items on sale

[mlalley]

When I try and edit a product to put it on sale I choose the option that says “Display “on sale” icon on product page and text on product listing” and then I choose the option reduction amount or percentage I go for the amount such as $10.00 I don’t use the percentage and in the store the price is incorrect. Here is an example:

Pre tax retail price: $449.99
Tax: 8.00%
Retail price with tax: $485.9892.00
Reduction amount: $10.00

Price it SHOULD be in the store (TAX EXCLUDED): $439.99

Price the store shows: $440.73

I hope you understand my problem if not just PM me and I will try to explain it more. Thanks PLEASE HELP this is a BIG problem for me.

*note: I have chosen the option to not include tax in my prices. (I have also changed it to show prices with tax and the problem still continues)

Did you ever get an answer to this?

The problem is that PS apparently gets that price this way:

SALE PRICE = ((RETAIL PRICE * SALES TAX %) - REDUCTION) / SALES TAX %)

(it applies the tax, takes the reduction off the full taxed price, and then removes the tax)


instead of the proper way which would be:

SALE PRICE = RETAIL PRICE - REDUCTION


I don't know why it does that. I'm using only percent based reductions at the moment and it seems to avoid the problem ... maybe.

It is the getPriceStatic function in classes/Product.php where the reduction is done. Try moving the"Exclude tax" section below the "Reduction" section.
