The answer:

"Hi Buyer,

We are raise the price As Chinese New year is approaching, worker in factory had
already gone back home and having new year holiday now. So our razer supplier have raise price for the limited supply.
If u didn't need it urgently, i suggest u could consider to purchase from us on around early of Feb.
Pls note. Thx.
Carrie"
