if a house cost 850k, not many people would have the cash to pay it off at once. thats why people do mortgages, it allows you buy the house and builds your credit.
I think the shirt you are looking for is 833562. They no longer have the V pattern in the front and the material is slightly different. I asked Nike Rep about these shirts and they said they are just out of stock on ndc. You can still get them on footlocker/roadrunner and many other sites.
