This may sound crazy but, honestly, I've never had such good service. Young men, mostly, who were knowledgeable and so helpful. Don't google for wood, most places are very expensive. Pieces that were £15 on Google were £4 here. 1.8 metre slats at £1.20. Great company.

Another delivery from Alter Supplies today. Amazing service even for a relatively small order. Timber and slabs delivered promptly by a very cheery young man! An easy 5* given!
