Tonnes to choose from, both flowers and vegetables, they have 2 price brackets, 28p for the smaller packs, and 47p for the larger packs. I bought 13 packs for £3.50, something which would cost more than £10 at most other places. A lot of the flowers are still ok for planting now, and there are some veg, radish, spinach, lettuce, cress etc that's still good for sowing in may! Or you could stock up for next year, or late this year =]
They seem to be different prices at different stores, but somewhere between 25-29p on average.
and loads others!
rep to stevey_p7 for posting this deal a couple of months back, I thought more people might benefit from it if posted again =]
