I dont think so. If you dont use it, you just waste 17$ for nothing and waste a space to storage the sd card. You may thing: it's a tiny space, but try to have hundreds of tiny thing... your house will be a mess.
My father and I used to had a ton of sale off thing which i thought i save some money here. But in the end, they are used for nothing, corrupted, failure, or my house are too full and i have to give away them. Wasting alot of money.
Now, i set a rule for myself : before i buy something, i will question:
Do i need it ?
How many time i gona use it ?
Then decide to buy.
Because i find out: almost thing we buy, we thing we will use sometime. But actually, we never use this. Or when we need to use this. We buy it with no sale off. BUT buying one thing is still cheaper than buying all sale off things.
