Feel free to make as many samples as you wish. It's no trouble. The big link at the bottom of the PDF email will save you entering data over and over again.
If you purchased documents you can amend those too. Use the same link to amend your order. Enter voucher code 'ADMIN' to update the original order.
* Changing dates is fine a few days either way. Changing dates in a pay sequence to get items free is not what this was designed for so please play fair.
You can reply to the email and we'll try to help. Usually we can change small things like spelling errors and dates. Anything more and we can offer advice but you will need to submit details online.
