Entering one or 2 incorrect letter in "error" would prevent this no?

Possibly.

Some companies can put two and two together and link the modified address to the original.

keep in mind that some companies (for example Nike) completely disregard billing adress as long as you don't trigger their anti-fraud system.
To avoid doing that make sure to DON'T copy and paste card numbers, just slowly type them like a normal person would do.
Also make sure to confirm 3DS (if your card has that)  first time it asks for it.

Basically focus on placing a correct order on the first attempt, if you fail then i suggest to use different account and card (details ofc as well)

Also this is a little side note:
I tend to get way less cancels when placing an order with express shipping and to everyone's knowledge they refund that as well

Cool thanks, I'll try this

Absolutely.

That why I said "some companies" In my previous post.

To be on the absolute safe side, I always change everything to a completely different credential.

You may as well do It right the first time around. The benefits speak for themselves with every SE thereafter.
