GSF do a 40%discount most weekends but I dot have one close enough anymore.
When ever I've priced GSF against ECP, even with this high discount, ECP usually wins...
However CP4L is always worth a try for a bigger order as they discount more, the larger the order, and usually better both GSF & ECP.
(None of them are near enough to me to collect from)
Why? It All appears to be the same parts to me?
