I'm no rep, but just because one source is great for one situation doesn't mean they are another. Case in point my FAVORITE source is pricey with a minimum. When I wanted to give a few vials of trenA a try and already had two, it makes no sense to hit an expensive ass minimum and get less gear when I have no idea how tren is going to treat me. Plus if you don't try it, you'll never know if there is something better out there. I'm a loyal customer to about 4 sources and I use others. If one is shutdown or another is having a killer sale it's not a gamble for me, because I know them.
There's also the matter of forum politics. I had a rep try to lie and call me out as a punk, which can get a guy blackballed, but I have dealings with enough reps and sources that know I'm solid that that shit just bounced back on that rep and made him look stupid lol.
