Yes, JS, 'appro' is virtually unheard of in Canada (as indeed is the Welsh 'ap' !). Since I moved here in 1981 I've observed that the whole notion of buying 'on approval', as my grandfather used to say, applies to virtually anything. If you don't like it, take it back and if the store wants any kind of reputation they will certainly exchange it for credit and in most cases be prepared to give you a full refund up to 30 days after purchase.
13D Local loops is acceptable, just that it's unlikely you would hear a phone engineer use such an expression here - I never have.
