The other place to look is one of those big remainders type book shops or the book clubs who come to offices with discounted stuff.
I have picked up very cheaply a couple of big fat diy manuals. Really handy to have kicking around for basic info like concrete mixes or how to cut coving or how to make a step in the garden.
The good thing about books is they don’t need the electric or WiFi working!
Loads of really helpful folk on here too.
My best ever tool buy as a DIYr is a DeWalt 18V li-ion cordless hammer drill. For years I struggled with budget cordless drills. They were all crap in comparison. This gets used so much it’s worth the big outlay. I wouldn’t necessarily buy the same brand again but I would buy that quality again.
I’d rather plumb than plaster!
