Can a feeder site link directly to the main site?

[Firestarter-SEO]

I have a client that has several coupons sites. They have about 15 different URLS all of which are [city]deals.com all of the domains have coupons lists that are relevant to that area. Other than the coupons there is not any other content on the sites. There is a Main site however, that has coupons, content, store locations, blogs, news etc... The coupons on the feeder sites are displayed differently than what is displayed on the main site. They are also categorized differently. So the question is on the feeder sites can they have the coupon link directly to the store page on the main site?

Yes, I'd definatley do that. You are just cross-linking form other domains onto your own site. If the domains are registered in different IP Ranges even better.
