Looking for some products

Hi all, wondering if there is someone who could help me, I am looking for somewhere that sells 12" human hair, either on the weft or bulk dosen't matter as it is going to be bonded in, also my gluepot could now do with renewing and I can't find anywhere that sells these at a decent price, everywhere seems to be selling low quality products now at rediculous prices, I would prefebably prefer to order from the uk but if you know of anywhere out of the uk that has cheap postage and good quality products could you please let me know, thanks girls!
