Do not worry about it, in 2 weeks or so you will have plenty of choices. Those people hoarding gpu's will start selling at 80% off.
Why would they sell it in a discounted price?
Facebook group CryptoMiners PH
Some members are selling their cards

Thanks for this. Is it okay to use second hand cards?
I would not buy anything if any decently priced cards are not available. Best you can do is hope Ethereum tanks, Metropolis goes into effect, and miners start selling cartfuls of GPUs discounted.
What do you mean by this, sir?
