Shipping
This stuff is sent from heavrn and will continue to be in our lives for years to come.
Wish it could come a little quicker, but reasonable.
Competitiveness
I checked the ingredients, and histablock is virtually the same at less than 1/3 the cost.
Not as well as xyzal, but adequately enough to block certain weed and tree allergies.
I am not 100% cured of allergy reactions but histablock has made a big difference.
