Phone up Pro-jump and tell them what bits you need and ask if they accept postal orders then get to the local Post office and get a postal order cross it with there name and only they can cash it then when you send it off 1st class and get proof of posting (costs nothing) this gives you insurance if it goes missing
The sooner you do this the quicker you will get your bits every day you wait for a reply here is a day you won't get your bits
