I honestly don't understand why the upset. If how a business does their business, there are sooooooo many vendors that can be chosen instead. If you're willing to jump through the hoops, go for it. If you're not, move on to someone else. People have complained about a certain vendors practices for over a year. They are still doing a strong business so there must be enough people that do not mind how that vendor operates.
There were quite a few new vendors that went through some growing pains. I was fortunate that my vendor managed to go through them and not have to close when a certain limit was reached. They did go through a period, very short few months, where it took 7-10 days for the order to be processed. They have since moved into a B&M, hired more staff and are thriving. It was worth the little bit of growing pains and I'm super happy they are doing so well. This last order I placed on Saturday night, I received shipping notice yesterday.
I had wanted to try one of the vendors that, for whatever reason, just haven't expanded their staff and continue to have those windows of opportunity to order. It doesn't fit with how I want to order so I just choose not to do business with them. I figure I won't know if or what I'm missing if I don't sample them. I think it would make me more upset if I finally got to try them and then had to jump through the hoops to get more. So, since I know it would upset me down the road, I choose to not even try to begin with.
All the complaining in the world obviously won't change how they do business. They've been doing it the same way for well over a year and still have a fan base. Why would they change? It works for them.
