By the say, I believe you also sell ●● and ○○ at your store and am wondering if you could give me 20% discount as well. (I saw them on ○○ (online website))
If so, I would love to introduce them to our customers.
Incidentally, I believe yous shop deals with ●● and ○○, but can I purchase them with 20% discount, either? (I found out them on ○○ (the on-line site).)
If yes, I would like to introduce them to my customers, too.
