I'm here
I've had a few technical difficulties with the mod I'd installed for the coupons. I asked the person taht did it to update it and make some changes and in doing so they cocked it up and have stopped replying to emails.
Instead what I've done and I think long term it will be better is to do a proper loyalty scheme so basically you get a point for every £ spent and that then can be redeemed on the next order. Each point is worth 5p so the same as a discount, but it just means everyone gets them.
I have a feeling it might cost me more money because of this, but hopefully it might encourge people to come back more as the savings are stored on the site.
I'm still implimenting the loyalty mod at the moment but if I can work out how I'll still honour the discount coupons as well.
