On the web, these sentences could be found:
1a. He made transactions outside of Amazon Payments.
2a. He made sales outside of Ebay.
3a. He made wire transfers outside of Bank Of America.
Dictionaries say that "outside of" means "with the exception of". But when I substitute this sense of "outside of" into sentences 1c, 2c, & 3c, I get:
1b. He made transactions with the exception of Amazon Payments.
2b. He made sales with the exception of Ebay.
3b. He made wire transfers with the exception of Bank Of America.
, which is awkward. It seems that "outside of" as used in 1a, 2a, 3a means "not through" or "using methods other than". This distorted usage seems popular with banking and other online sales field. Could it be technical jargon?
