I assume this is too late for you IS, however I know that 'Top Tackle' in the Port Road, Letterkenny will have a pound or two spare after 4p.m. on Friday.
We ordered some but they had to order a minimum quantity so there's a couple of pound going spare - €12.50 / Lb.
I managed to get some in Bertie O'Neills in Bridgend. €5.20 for a wee shrink-wrapped bag. Are they meant to come like that? The worms were dead and dyed red. I thought you bought them alive
