Response from BPF Websales
Thanks very much for your review and thanks for alerting us to the fact the email you received encouraging you to consider leaving a review, mentioned a voucher code - this was an oversight as we sacrificed our review voucher codes last year, in favour or dropping our component prices across the board for every order, so it sounds like there is some wording in the email template still, which needs removing. I asked if you'd be kind enough to forward me the email in question, so I could get that amended by our web developers, so if you can send that to jason@bpfonline.co.uk which you can hopefully copy and paste into your email system, that would be most helpful. Hopefully the advice I gave about signing up to the newsletter to get the same discount level, is something you will bear in mind.
