Hi lee Pryor,
Do you still use jogPost. Have got a quote from them, but it seem expensive once you add vat.
Do you manage to get a minimum 25-30 regular customers per 10K.
Yes we still use them. We are planning to deliver 800K-1million again this year.
Its true they are not the cheapest option but they do do a very good job. Its one of those things where you get what you pay for. If you dont want them to end up in a bin or bush or go through the door in a huge pile with 10 others then you should expect to pay more.
I like the way the drop is GPS tracked and monitored. They also cope very well with large volumes at a time.
In terms of your results there are too many factors to answer your question. However the most important factor is making sure they actually get delivered. Doesnt matter how good your design is if they go in a bin.
