Thank you indeed. It was really fast and lucid.

A good deal - an arrangement between two or more parties (business or person) which suits both sides. It means that a good or low price was negotiated. Ex: We negotiated for the oil contract and in the end we got a good deal (suited everyone at a good price). Offer - means you are offering another party something, a commodity or service. In retail it can mean a low price on a product for a limited time. Ex: We have a range of garden furniture on offer for 10 days.

Deals = good bargain of something that has been arranged by a business, great business arrangement for something Offer = on sales item/cheap things Example: Deals = That company has great deals on their vehicles. Example: Offer = The blue chair in that store is now on offer.
