The biggest problem you wil have is that your items are probably heavy so shipping costs will be too high and you wont be able to compete with asian sellers. The high cost of post will also mean the consequencies of a paypal claim will be high and so reg post will be required. This in turn will make it even more expensive.

Keep in mind if you sell a $10 item and total cost including shipping comes to $40, the buyer will be expecting a $40 quality item. That is, quality of your item from their persepctive will be benchmarked against total cost not actual, this can result in lowered DSRs and general complaints.
