Lenovo y530, 1GMJ model at rm4250, is it a good deal?

At lazada birthday sales during yesterday. From eit store. The price is rm4550 yesterday, and additional store voucher rm300, so final price at rm4250. Check again this morning, the price become rm5088. I already place the order yesterday, but haven't make payment, still thinking wanna to take it or not. Looking at yesterday and today price, it make me wonder that nowadays the profit margin for selling pc\laptop can be still so high?
