....might be a nice sticky thread....
Anyway here two tips for the Dutchies I guess....
#1:
I needed a security bit set like this to remove some screws from my Ms.Pac Man marquee retainers, a set like this:

I was shocked to find prices like this:
http://www.gerritse.nl/Toebehoren_boren_zagen_slijpen_en_tappen/Schroefbits/Schroefbits_sets/126731/veiligheidsbitsetje_33_delig/€25 EXCLUDING 21% VAT !!!
I know, a GOOD quality bit-set is more expensive but this seemed to be one of those cheaper sets....so I dug around a bit more and found this:

And it cost just €4,30 INCL. VAT !!
http://www.toolstation.nl/shop/Gereedschap+accessiores/Bitsets/Veiligheids+bitset+Kort+33+delig/d80/sd650/p92461Now....I need to use these bits only very rarely, you just need to have them around so I grabbed one of these sets.
Toolstation.nl looks to have other nice prices for loads of tools too. Some brands, some "no name" stuff....they deliver to businesses and private persons and ship for free if your order is over €10
They also have a number of "counters" across Netherlands, I went to the one in Schiedam because I needed the set "now"....
www.Toolstation.nl reminds me a bit of Harbor Freight although these have proper shops AFAIK, toolstation is a web-store with some "counters" you can visit...
Anyway, worth having a look at !
#2: (this is actually a stolen tip from Etienne, I have to say in all honesty

)
Polyester Putty, often referred to on the US sites as "Bondo" is available from lots of brands....I bought "Alabastine" in my local DIY store:

This stuff is priced around €13 for 200 gr. Pretty steep IMHO. Also what I REALLY didn't like is that, contrary to the "real" Bondo, the hardener had almost the SAME color as the "main" stuff. This makes it _very_ hard to know if you have mixed it well enough !
As mentioned, Etienne put info about this alternative in some thread here:
This is for sale at Action stores in The Netherlands (
www.action.nl)
The price is only €4 for 485 gr., that's more than twice the volume at 1/3 of the price ! The best thing is, the hardener is RED (just like Bondo) and so it's very easy to know if you mixed it well enough...haven't used it yet but will in a few moments

Anyway, it's worth looking around for alternatives for the expensive "A" brands that often you just pay a lot more for just the brand....
