Crazy - No not really.

I use two separate carts:- samples.XXXXX.co.uk and XXXXX.co.uk.
With the samples cart I need to stop any second or subsequent orders from being placed - some people are just plain greedy!
Sorry if the answer is obvious but is sending me round the bend.

I use 1.3.8a
MySql 5.0.67
PHP 4.4.9

Any suggestions please,

Martyn
