I've bought it from NBA2king multiple times and overall, the experience is excellent. The primary reasons are:

Because I need 2KMT and they're always in stock, and the cost is generally lower.

The speed of delivery is quick in normal conditions, and it is reliable and safe.

There are numerous payment options since I use my debit card for paying.

Always make available 24/7 support Contact the customer service anytime should you have any concerns about the transaction.
