As the postal strike starts today, many small businesses will be affected. Here is a tip. Try using a service like Yousendit .We have used it for a while and its great. You can send 100M for free and beyond that for a nominal fee.
This works well – and for the first time we used the paid service from yousendit instead of the post
I have no commercial affiliations with this company. But postal services will soon realise that the Internet gives people more options than posting paper!
