I have spent the last couple of days adding new stuff to my website but today I've just given up.
The only person who is making any sort of money out of my website is my supplier they just keep upping their prices without advising me so when I go to place an order I am making a pittance on a sale.
I'm soo stressed and tired and broke that I'm thinking of just giving in and closing the site and not bothering at all.

That's a nuisance , maybe you should stick to selling on , or having your own shop on ebay ?
I hope you get it sorted out and can be guided to make the right decision , and that you'll feel better soon , with kind regards , ~ martin .
