Vostro 7510 price drop

I bought this laptop literally 20 days ago the price went down from 1568$ to 1399$,  I told them if they have the same policy to give a discount to match their own price within the range of 1-2 months they said no but you can return it and buy it again, what a huge inconvenience, I am thinking to return it and buy another brand that is committed more to their pricing strategy.
