Amazon purchase

So ever since I upgraded my phone, I have obsessed over cases- especially wallet cases. I love that there cases are multi functional and pretty. I found these on amazon. So, I am definitely into finding a bargain. These cases seem nice. My only problem with them is this--
1. Their smell is extremely strong. I don't know if its a different glue that they use in the U.S. but man as soon as you open the package, it gives you a headache. I've started to air them out for a few hours before I use it. The smell gets a bit more faint with time.
2. They take a couple of weeks to arrive- this stuff is mainly coming from China and Korea- it takes it sometime to get here. Also there is almost never a tracking number.
The pros of course are price. They are priced so low, you don't mind buying a few. I wonder if you'd just be better off buying one good one and calling it a day. What do you think?
