Ahem, what errors these customer cause me, how stupid they seem to be, always causing me the very same errors over and over again. Everything is set up plainly, give me the credit card number and I will withdraw the sum from their account. I do not get it, I have even removed the figures on tax and charges added since that looked too messy. Charges are the same as mail order, go read a catalogue if necessary. Further, I have not added a lot of boring text and information about our policies and stuff that no-one likes to read anyway.
Most customers realize that our low cost items admit no refunds or warranties.
And a child can understand that we can not guarantee delivery within a few days or so, we first have to find the item at the promised prize somewhere. Or at least at a nearby prize. Or a close to similar product. Then I send these visitors nice letters every soon and then to remind them going back. I do not understand, some responds unpleasantly though I only want them to realize that I, too, have to make my earning somehow.
