Order # 111803437

I haven't downloaded the item yet.
At the last page for check out I had 15seconds at that moment I clicked on the payment and it went from charging me $6.73 to $14.95.  I can't pay that price for that item now.  Can I please get a refund or store credit?  I was only getting that item for the textures.  I don't want it at full price.
Thank you for any help you can provide.
Jules
