Last few orders (checked that they were all ex-stock) arrived next morning ... so far all ok here. Sorry, not much help.
I'm the same. I use RS all the time and have done regularly for about 9 years now (I was out of the country for a few years before that). They've dudded me once, which was on a lithium cell that had to come from the UK by boat, and it never arrived.
Other than that, as long as I check that the stock is local (and yeah it's a pain as you have to individually check each item before adding it to the cart) it has always arrived the next day (which given it's always coming from the other side of the country is actually quite an achievement). The stuff coming from outside of the country always arrives within the 5 working days, and mostly sooner.
So, no they seem to do good work for me also. There is something strange about being able to order a 15c resistor that has to come from the UK by air freight and not paying any postage.
