I've had three in total, paid a deposit on a debit card for a training course, a month later they took the rest even though I had, in the meantime, decided to return to Ireland. The course was for a HGV licence - had no start by date, no finish by date, no materials were supplied - foolishly I was badgered into paying the deposit (I registered on their site for more info) and a month later they whipped out the lot - all legal.
Secondly I paid a deposit on a car, went to my bank, sorted out all the loan details, sent back to pay two days later (as agreed) and, cough, "another salesman sold it - sorry mate".
Again the sale of goods act does not cover me if the retailer goes bust.
I had 2 Suits (with 4 trousers) to the value of €1500 adjusted to fit me not two months ago - I tried to pay up front as this business has been trading as long as I've been around - he would not hear of it until I was satisfied. I'll go there again.
