I have done tier price by creating a mySQL import file with Excel. My price structure is pretty simple and my items have same price there for it is easy to do.
But I couldn’t find how retaled product, cross-sale, up-sale product are recorded in the database. Can anybody point out?
I read posts here about using web service API to do this, but I am a programming idiot and have no idea how to do it. Is there a tutorial for this and example available?
Many thanks for all comments
