Trade link if needed:

But best use steam tradematcher (Stm) rather.

Regarding card trades:
If I lack duplicates to trade or if you offer a 2cent item in exchange for my 100cent one, chances are your trade wont be accepted.

A few issues with steam:

1. https://test-steamproxy.haloskins.io/discussions/forum/0/1643167006258143373/

2. market locks
"You have logged in from a new device. In order to protect the items in your inventory, you will be unable to trade from this device for 7 days."
Same browser, same pc. Thanks Steam! Appreciate that my trade and market gets disabled for a week.
(this seem to have improved after many years but no longer really use market anymore)

3. Steam removed the Paypal pay option, forcing me to do purchases via other sites spreading my profile over gog, origin, indigala, groupees etc.
But all these are good:

as its totally possible for these services to shut down, example:

and Desura.. and groupees Jul 2022 making you lose all your products. no refund.
Or implement crazy policies like credit revoking when overhauling systems.

They never saw me again, sale-wise, but the damage was done, lost credit.
Some users even complain that their trustpilot reviews get deleted, advise serious caution in dealing with green men. https://uk.trustpilot.com/review/www.greenmangaming.com?languages=en&stars=1
