I've ordered a fair bit from Tredz and found them to be OK for stock IF you read the listing carefully
In Stock means what it says
In Stock with Supplier generally means it'll take a few more days, but could be a bit longer
Due in Stock on (random date) means come back next year
Also I don't think they've been mentioned, but I've had a few bits from Tweeks Cycles and found them to be good value.
Thats quite a common stock system, I worked on (for IT eCommerce) a similar system for a builders a few years back. In Stock with Supplier was needed as we'd often only carry a limited stock of the 10000s of parts a builders merchants might have, and we'd also state how many we could get. Due In Stock should be accurate to the next delivery, and that could be next year with bike parts!
I've added Tweeks to my sellers though
Have predominantly used Merlin in the past but just recently for stock availability have been using Tweeks in Wrexham.
Fortunately for me if it is something I can carry I can collect on a bike ride as it is about 20 each way.
However I did order something mail order last week and it arrived next day (free postage over £50 which my order was)
Merlin have served me well over the years but my main gripe with them is that they vet reviews and never publish less than a four star so product reviews can be a bit misleading as you don't get to see the bad reviews.
Interesting, I did read the reviews on Merlin for what I wanted (couple of rear lights) but I always go external for review and found a good road.cc review for the lights.
