Hi Apple,
I have been in the electronics business for the last 25 years(small retail shop). I am presently in the process of selling my shop as it is IMPOSSIBLE to compete with the large warehouse style outlets and now all the major supermarkets are on board too!! So dont waste your time and money even contemplating the idea regardless of how cheaply you can source them ....guaranteed by tomorrow the major supermarkets....the german ones in particular, will have them cheaper...and a three year guarantee!!
By the way...anyone interested in my shop??? hehe..goin` cheap!
