Following on from my topic about the pancake replacement pipe I have had a reply from Ollie at THS
Thank you for your email, and thank you for the interest in our products.
We tend more to offer discounts to club forums rather than doing group buys. We find it tends to work a bit easier and requires a little less organisation! We do this by offering a discount code to club members which can then be used on our site against your purchase.
We could offer your forum a £10 discount on the PCR pipe on it own.
Kind Regards
Ollie
That works out better as we can buy them at our leisure
