You can shop around in your local place to see whether there is any glasses store having discount activities. Some opticians will put the old season sunglasses to the discount section for customer to chhoose.
I think there are many places for you to buy some old season sunglasses. Here is my several suggestions. First, you can go to some big shopping malls. As we know, many brands would deal with their old season sunglasses when the new arrivals come and the price is really reasonable and affordable for you. Secondly, you can also go to some online websites. These online stores often have some preferential activities. At last, I suggest you to go to some second-hand stores. You can find some surprises there. The sunglasses are really cheap and some are even quite new. You can definitely find some surprises there.
Go to optical shops, ask them if they have old season sunglasses. And also, you can find it online. There are more and more people buy glasses online. Because the price are cheaper, and it is more convenient to choose the glasses you want, especially the discount is so attractive, sometimes there are some free glasses for you. So you can try to find some glasses online in a reasonable price. i prefer firmoo.com and coast.com. Hope you can find your glasses.
