Not sure if this ought to be in this thread or a seperate one (Kevin please move it if it's wrong).
I am thinking of setting up a business delivering animal feed around the local area.
I want to be able to group postcodes together so that on Monday I would deliver to this geographic group, on Tuesday I would deliver to this other geographic group etc.
Also restrict customers so that if they live outside the area then they cannot order goods, unless they contacted me first & asked for that postcode to be added.
If they wanted the feed delivered on that geographic area's day then delivery would probably be free, if they wanted it on another day then a charge would be raised.
This is all hypothetical as I have no idea if the business is feasible or not but I think it would be a very interesting addition to be added to Zencart anyway.
On a personal note I have no PHP/programming skills but will help wherever I can.
