I've used RS for years. Free next day delivery for anything in stock in Aus, and ~5 working days from UK stock. It has been getting more and more common that stuff wasn't stocked locally, so there was pretty much always a 5 day wait.
Last order I noticed it's now $12.95 delivery for any order under $70. It's probably not unreasonable, but I didn't see any announcement of the change.
Digikey is always 5 days away, and shipping is usually $25 for anything under $60. So for any significant order it's now a bit of a wash between the two, but Digikey has a much broader stock base.
I'm now far more inclined to use Digikey than RS unless it's a "need it yesterday", whereas previously I favoured RS.
Did anyone see any publicity surrounding the change that I missed?
