Big Bike Cover -Where to buy in Chiang Mai?

Does anybody know where to buy a big bike cover (for XR250) in Chiang Mai. Tesco seems to never have them in stock, they always just have size M for Dream style bikes for around 400b. Thanks!

 

Thanks for that, I will check out what Big C has.

 

Ok, I got a cover at Big C today. They had two brands/qualities available in size L. Thanks for the tip.
