hello!
thanks for the reply. no I was referring to a price difference between the stores product page and the checkout page . the product pages show the correct prices ( including the shop owners markup ) but when it gets to the checkout page the price now shows incorrect price which looks like only the spreadshirt.com cost. This would mean that we would be selling items at NO PROFIT.
I am now getting reports that some people are seeing correct prices and some are not. I will wait another 12hrs and then update this thread. ( this may be a spreadshirt.com store system and not your plugin )
