I just called them to follow up on an outstanding order from the 13-14 October, so about 5 weeks ago. The operator cited their supply issues, but that stock was finally in for it. She said she would speed it along for me and it should arrive this week.
I've noticed issues across the board to varying degrees too. Since covid and the implementation of brexit, anything last minute that you might need just isn't possible anymore. Where before I could replace something within a day or two, stuff now takes at least a week to arrive.
So in answer to the original question, it is still having an impact, and it's not one that I think will ever go away compared to how things were before now that the 'just-in-time' supply chain has been thoroughly disrupted. We just have to factor longer delivery times in now whoever we go with. I recommend not waiting as long as I did to chase it up. As Paul has said, ring them up to enquire about stock levels (though one would expect this to be reflected on their website), and ring up after a week or two if stuff hasn't arrived. They may have the stock but just not have gotten to your order yet.
