I got an email from them this morning:

I would have been tempted by their electric propagators but I've just ordered one from somewhere else, and I already have more seed trays than I need ::)
I looked at their catalogue again this year, don't know why, i find them expensive nowadays, they were quite reasonable about 8yrs ago.
Also, their catalogue is all over the place and you have to contact them to ask if the prices are right.
I get most of my seed trays etc... from Wilko's cant be beaten on price.
