So in the end, we can say that both companies are authentic and reliable due to 2CO payment gateway which is offered to only those companies which provide best services to their customers and they have authentic Geo location too.
2CheckOut (2CO) is an e-commerce platform to facilitate secure fund transfer between two parties involved in some kind of transaction over the Internet.
However, to say that the companies are legit just because they use 2CO, is a VERY tall and unsubstantiated claim. 2CO provides services to merchants from almost all over the world.
Their policy of taking you on board as an affiliate merchant offers quite a few loopholes that can conceal your real identity. I have personally conducted some research on 2CO and other similar e-commerce portals, and I've found out that a company from country A (a 2CO affiliate merchant) shows being based in country B.
Also, it is impossible to say that because A uses B as an e-commerce gateway, A provides the best services. White-collar criminals have bank accounts mostly in reputable banks.
Last, 2CO is quite unique. If you read their ToS, you'll find that they "encourage no-refund policy". This in its own right is dubious. How can it encourage a no-refund policy? Does it make sense?
I think it's enough to counter your marketing-driven narrative above. Please stop misleading the reader.
