Postage Costs

Has anyone tried the new Ecloths for cleaning? They are marvellous and seem to clean anything and everything. Especially good on glass. I am sorry I have had to remove the free postage on some items. It became complicated for two reasons. First, postage is quite expensive now and on smaller items it really eats into the small profit margins and we never charge for time or stationary used such as post office boxes or padded envelopes. Second, it makes the paypal calculations very complicated as the postage is automatic.
