Yes, the prices are very low compared to market but I believe that he gets that because a bulk purchase he has done and prices are wholesale bulk prices and hes just selling them individually as well. I am sure by the time these get to the shops, an extra 15-20% keeps getting added per hop. Most of what you see in shops was directly imported from US I think like Meg/Mothers (my personal thought only, haven't checked).

Even better is the fact that I scored 15 bottles at the local Grocery Outlet in the automotive section, clearance priced at $2.99 each! What a score!"
Also, around 15 days ago, on the UK 3m website, the prices for all these products were slashed in half so the performance finish was available at around 4.99 pounds. So that makes me believe the prices can get low for these products.
Disclaimer: As i mentioned earlier, I have also gotten to know Saad Piracha through this thread. I only posted all this incase it might help anyone. If somethings wrong with the products, I'd probably be affected too (I seriously hope not InshAllah).
