flat price and full price

Not too clear on the readings…

When a person buys a bond between the coupon dates, do they pay the full price or do they pay the flat price?

Who gets the accured interest? The buyer or the seller? If a person pays the flat price, does the seller keep the accrued interest? if the person pays the full price, I assume the buyer keeps the accrued interest?

The full price.

The seller.

The buyer pays the full price (not the flat price), so the seller receives (and keeps) the accrued interest.
