If a web commerce provider is summarily blocking every IP address on his
copy of the list, chances are that they will not change to a policy of
only blocking exit addresses, as that takes extra thinking.

Of course such a list goes out of date faster than a phone book.  That
is another reason that using a list is an exercise in futility.  Even
more thought required to see that.

Thus it would be hit or miss to try to access their website using Tor. 
If they do not respond to a suggestion that they learn more about Tor, a
better choice is either to move on to a competitive website or to move
our relay (exit or not) to a different IP address.  Those options are
already on the table in this thread. 

The situation would change if Tor became the normal means of accessing
Internet commerce websites.
