Hi,
Please provide an email address I can send you a video;
For reference, the following occurs;
customer submits an offer of £100.00
Offer is accepted and is added to the basket + VAT = £120.00
Instead, it should be;
customer offers £100.00
Offer is accepted and is added to the basket INC VAT = £100.00 which is 83.33 + 20% VAT
