[QUOTE=ostap77;741705]if I came by a book-store and asked for the book that just came out but it turned out that they didn't have it yet, coud I get an anawer like this "Why don't you check back next week?" Yes. Would it be "check back next week" or "check back at us next week"? "Check back next week" or "Check back with us next week."
If I were right in the middle of something and didn't have time to talk to a person that was calling me, could I say "Could you check back with me later?''? Only if the person was calling you to check something (e.g., to check if something has arrived); otherwise, I'd say "Could you call me back later?"[/QUOTE]
