I agree re the lack of shops outside of London and also the lack of thought in putting things online in a timely way even though that's where most of the loyal customers are! Also not giving loyal customers a single discount (save for the sale) across the year. Toast should at least introduce some sort of loyalty card or a discount code if you spend over a certain amount.
Like others, I am broadening my horizons in terms of looking elsewhere. Folk is coming up again and again for me, although similar prices to Toast. Also I am looking more at Vintage: cheaper and more sustainable.
