REGISTRATION FEES

Registration fees *should* be paid in advance at the registration rate shown below using PayPal.

If you do not have a PayPal account, then cheques (drawn on a UK Bank in £ Sterling and made payable to ‘Applied Vision Association’) can be sent to Alexa Ruppertsberg at the address below.

Cash or cheque payments will also be accepted on the door, but credit card facilities will *not* be available. Please, make sure we know that you are coming by dropping us an email, if you neither submit an abstract nor pay in advance.

Members registration @ £25

Student members registration @ £10

Non-members registration @ £35

Student non-members registration @ £20

Non-student registration plus membership special offer @ £45

Student registration plus membership special offer @ £30

Grant-holder’s registration (includes membership if not already a member) @ £80

As many of you will know, the AVA has moved to a policy of a one payment, life membership fee (of 25.00 pounds sterling). One way in which we hope to offset some of our meeting costs is by introducing the 'premium' category of registration fee. There is no obligation to pay this fee, and we expect that most people will pay either the 'student' or 'other' rates as appropriate. But, we do hope that grant holders might consider paying the premium rate. In all cases, a receipt will be provided on the day for the fee paid, but this will not indicate the category.

HOW TO GET THERE

Information on how to get to the University of Bradford can be found at:
