I think it is RS who are getting expensive.
They have always been my go-to supplier but they are pricing themselves out of my pocket these days. e.g. £7.99 for a 300ml can of compressed air !!! (for blow cleaning keyboards etc). RS seem to have decided to move away from the individual engineer or the small engineering team, towards large companies and construction. Nuts and bolts now only available in quantities of 100, 500 or 1,000 for example, which used to be available in 1's, 5's and 10's.
RS used to the the gold standard in the days before the internet, because of their hugely impressive and well organised stock control and distribution system; which would enable an order to be placed and posted to arrive the next working day. And I bet we all remember the equally impressive RS (paper) catalogues, which were so fascinating to read through !
Luckily, now we have the internet; and there are many other companies around who do an equal – or far better job – of supplying components. We just have to find them.
Rutland and GSProducts are two that have impressed me.
