Oh how I would love to use another service other than AP to send my parcels but the reality is that AP are the cheapest provider.  I have gone round and round with different companies asking for a better price to send poster tubes and no one can do it.

Sendle did offer me 12 months of free Premium account if I signed up but their shipping prices were still higher than AP so I had to decline.

Someone else who finds them more competitive for their own needs might want to try and ask if they can have the free 12 months offer.
