A local merchant's I use is a small family run business but vey good with an excellent delivery service. I have noticed over the last few months prices are changing (upwards) and less is being shown as in stock, this does change though as new stock is replenished but it is very changeable.
BBC today mentions shortage of supplies due to increase of diy and small projects over lockdown, it mentioned that some larger projects may be delayed or postponed due to supply.
Plaster products, cement and wood supply is short and I notice some PIR products and Knauf Earthwool is a bit up and down in availability, hopefully I can get on with my project of a 5m x 3m posh out building/garden room. Swimbo wants somewhere to put her fitness stuff and I want a corner for for my extraction.
