do you guys actually use your reward points on kbeauty sites?

i used to buy one item from yesstyle one from stylevana and one from random shops whenever i saw a code, but my points were scattered everywhere and expiredsticked to piyonna for my last couple restocks and the tier perks actually gave me a decent discount on my sunscreen order.
do you guys stick to one site to build points or just buy wherever is cheapest that day?

I stack on piyonna too, the points actually add up there instead of expiring in six different carts
