Where do you buy pots/planters?

[dottyaboutstripes]

I need a new BIG one for rhubarb. Thought I'd ask for recommendations. I have lots of pots which I tend to buy in Costco as they are such great value but they don't have the right size/shape. Local garden centre is a bit pricey but I guess I could just buy from there.
TIA!

B&M and other similar stores often have big ones, they are starting to stock their gardening aisles now, so it might be worth a look. Otherwise you could use one of those big potato-growing sack things.

They were all half-price in Homebase when I was there two weeks ago. They're in administration so everything is getting reduced.
