Product : multiple prices for the same reference

Product : multiple prices for the same reference

Hi, 
I have a doubt. I need to have my stock in the crm in order to be able to send quotations. and the same ref might have differents prices. 

Let me give you an example ! I sell refurbished Iphone 6s. The ref stay the same "iphone 6s refurb" but I can source one at 300 us , another one at 330 and a third one at 345. 
I need to have this info in order to be able to decide what will be the price to send with the quotation. 

So a product (same ref) with different prices. 

Anyone ? Do anyone have an idea if it is possible in Zoho. In some solutions, it is called "product variations" (an automatic process). same ref, but with a "-1" "-2" "-n" at this end. 

Thanks for you help
