I notice all my local stores have stock of Switch's and no insane ebay prices (beyond the odd hopeful lister), wondering if this is a good sign that Nintendo have done a great job on delivering large quanities early on? or is it just slow sales?

sales seem to be doing fine

When it comes to releases, some places may be completely empty, slightly stocked, or loaded. Really just up to the region.

I've visited approximately 25 stores in my region and have had no luck unfortunately. Nintendo thankfully is consistently releasing out batches, so we'll soon be able to see people get a switch easily with no issue.

It's sold out almost everywhere here in Portland OR. Including Best Buy, GameStop, and all but one target. Also sold out on Amazon 

FeelsGoodMan , its still impossible to find in stores, but i was about to order from GameStop today

The walmart I go to has pretty limited stock.

awesome I am in Australia, lots of stock everywhere here, but very happy to hear it is selling well. will wait till their are more games before I buy personally as Zelda isn't my thing.

It apparently sold better in US than EU. I could order one right now on Amazon FR and receive it today. Other people on GAF from EU said that they can buy one pretty easily, it doesn't seem completely out of stock here.

I'm in Australia as well and like you noticed lots of stock but it's the standard grey , you have to preorder if you want neon colours.

Available on European Amazon stores and other online outlets, never sold out.

I'm not really surprised. Out of all the gaming sites in norway, counting at about five major ones I think, none of them had an article on the release day of the switch. No mention, no nothing. Not even a word about zelda. One site had a review (10/10), all the others were silent. I would say things like that is part of the problem.

Not to mention that the US is generaly more nintendo happy than the EU.
