Independent. Scottish Avian Supplies. I try to buy as much as possible from them so they stay in business. They just started stocking Harrisons, they've found it difficult to find a reliable supplier.
the two old guys that own it are great. They have loads of parrots. They take on rescue birds, I've never seen any of them but they have a lot of very badly plucked rescue cockatoos

Last time I went in there was a pair of gorgeous budgies.
The only thing I don't like is that when they open the freezer to get the palm nuts they had loads of dead white mice

(for the hawkers)
