Getting more stock for a business before a deadline

For my own home based business I am trying to get some extra sock in before a big event in August this year. Most suppliers either don't ship to most countries, or they are also waiting for stock, or both. Many do not even bother to reply to enquiries and their websites are very vague when it comes to where exactly they do ship to. Others do mention on their website that they ship to various countries, but after placing an order it turns out that they do no do that and they don't bother sending an email to mention that small detail.

Then there are those companies that use stalling techniques which go on indefinitely with promises that they are getting stock and other things.

How do these companies ever want to sell anything?
They can just as well close down if they do not want to sell what they are trying to sell as well as giving no or a terrible service.

To all those annoying companies out there: If you are not trying to sell anything via the internet, then get rid of your online shop on your website!
