“OK. Well, I'll take it.”

You're shopping for a new computer at an electronics store. After asking a salesperson a few questions, you're ready to buy the computer that he recommends. You say:

OK. Well, I'll take it.

Well...

You use "well" to change the topic of a conversation or to signal the end of a conversation. For example:

Well, it's nice to have you back.

Well, I look forward to working with you.

Well, hang in there.

OK. Well, it was a pleasure meeting you.

I'll take it.

This is the standard phrase that people use when they're discussing an item with a salesperson and decide to buy it. Aside from computers, you can also use this phrase when shopping for:

• a car
• a house
• software
• art

Notice that this phrase uses "I'll ___". One of the main ways that English speakers use "will" is to announce a decision that they've just made.
