This is an extremely good bargain - $4.99 for Swisse Ultiboost Absorb Well Co-Enzyme Q10 45 Capsules, usual price is $39.99 and cheapest I could find elsewhere was over $20. Note that reason for this low price is that this product expires at the end of this month so you may not be able to use it up completely. It's probably best to use it for sample purposes.

There's a shipping charge of $8.99 so perhaps you should buy other stuff in the same order.
