Platinum, or Blonde Hair Extensions on Aliexpress

I recently had to pay about $140 to get my hair colored because I didn't want to risk doing it myself-the colorist had to lighten the virgin hair to get the dark eggplant color I wanted. I was wondering if they sell aliexpress hair already blond, and if so, can anybody recommend any good seller. I need it be blonde in order to take the blue/black dye better. Thanks
