Just returned from my early-morning visit to Wyevale. These comments may not apply to all branches...
At this time of year GCs are often almost empty of plants, but all the display tables were fully stocked.
There didn't seem to be much cheap bedding. Strawberries were half-price (75p), and looked almost past their sell-by date. I noticed large tomato plants, with fruit on them, half-price, at £7.
Most of the plant stock was not reduced, so normal prices, around £7.
The seed sale is 50%, for selected lines only. I think that may include most vegeatables. I was looking for some seeds, but they didn't have what I wanted. I think it's an end of season clearance sale.
Right at the back is an area with remnant plants. They had a lot of sad-looking sunflowers, in yellow pots, for £1. They should be recoverable.
One curious item that did catch my eye - a chicken run, £340 - basically just a wire enclosure, and a wooden box for chucky to sleep in. It also had a plastic chicken inside - to give you the idea. Not sure if the plastic chucky comes with the set.
There weren't many people there. Maybe numbers will increase later.
