I don’t know much about british prices, but $15 for a bottle of oregano oil doesn’t seem that expensive, its like $20 here. But if the exchange rates is like 2:1, your bottle would be like $30 (US), which is a bit high. The way I look at it with euros is that everything is expensive, lol. For $20 US we can go to Mcdonalds 3 times (without tax) or get a bottle of oregano oil. I am guessing $20 euro would give you 2 meals at mcdonalds. In general, health products are expensive…take a look at how expensive probiotics cost. It should be like $45 US which I am guessin is like $60-75 euro.
