Purchased a 64 GB SD for 800/= from MultiPlan center. And then checked Daraz for a second one. Minimal price in Daraz is 420/=, almost half of what I purchased at.
Now Daraz seller's SD cards might be bootlegged and not genuine, but then again who guarantees that the one I already purchased isn't a bootleg either.
Conclusion : It's not worth buying from anywhere but online now a days. That hadn't been the case say even 4 years back.
