If you have an Amazon outlet, sometimes they can be a good source. Not necessarily sold and fulfilled by amazon, so kinda acting like an "amazobay" if that was a thing. Due diligence is essential in not getting duff goods.
Of course, ebay is the same, but at least it's not saying that it is it's own market place at the same time as letting other folks sell though it. You gotta do your homework here too, but some good deals can be had.
I've bought Neutrik connectors from sellers on both of these two platforms before, all seem completely legit. I've no reason to suspect that the items were counterfeit. But I did check through feedback etc. Bought Monster speaker cable from the US as an import on ebay. Seller was a genuine shop, all was well. Whether or not the Monster cable was actually required and that something a bit cheaper could have done exactly the same job is a topic of hot debate - time for popcorn!
I do just generally search the internet for what I want, and don't usually use google's "shopping" button as it tends to filter for their preferred sellers rather than anyone. You might be onto the 5th or 6th normal search page before you find a legit company selling what you want for a good price.
As with DIY stuff, sometimes there is the argument of it being worth a little price premium to get it all together, neatly and quickly shipped, less hassle and some possible help from the company. I'm sure I've bought from a company at a little higher price before, simply because they had a whole load of diagrams and helpful information on their site. Someone had to make all that info. available.
CPC Farnell are quite a handy place for all kinds of connectors and stuff. I've bought a few things from them. Once I had a mess of an order that took me a while to work out, however customer service understood and solved it quickly. Things do go wrong from time to time, it's how quickly they get sorted is what matters.
