They only sell in 2 packs and sometimes have sizes that are not the norm. For example, their glp3 comes in 12 mg which throws the math off for dosing. Sometimes the 2 packs can be a good value. Especially with their odd sizes as you can end up with more product for the price compared to others. Shipping was fast from Florida to West Coast it took 5 days. The klow is a much darker blue compared to others but there have been no issues. I'll continue to use them for certain products because i's cheaper than others.
