I'm designing a price list table for my database.
It will include Customer, Model, Start_date, End_date, Price, Currency, RRP
When I update a new price list, which is sent every now and then (maybe every 1~3 months), I need to update the prices but I would like to keep the records of what has already been raised.
Currently in system:
Customer - Model - Start Date - End date - Price - Currency - RRP
A - Z - 2015/10/20 - 2015-12-19- 120 - GBP - 220
A - Z - 2015/12/20 - 2999-12-31- 100 - GBP - 200
After updating new price:
Customer - Model - Start Date - End date - Price - Currency - RRP
A - Z - 2015/10/20 - 2015-12-19- 120 - GBP - 220
A - Z - 2015/12/20 - 2016-02-20- 100 - GBP - 200
A - Z - 2016/02/21 - 2999-12-31- 90 - GBP - 180
What is the best way to update the price?
I tried to google which solved all the problems until now as most of the search results is bringing up SQL price plans 🙁
I have learned MySQL 9 years ago in college for a few months so I know how to interpret the SQL scripts but I am totally lost when I'm trying to create anything from scratch.

I have two comments about your design:
I suggest something like this:
You could have a general price list and special price lists for special clients.
