Pricing Issue

Product is great and have purchased from Sams several times over the years, I do have one issue with my purchase. The Chlorine Tablets were on sale on line but not in store, I tried to purchase in store at sale price and wasn't able to because price was much higher. I ordered online and picked up at the store at the sale price which did not make sense to me.

excellent product at an unbeatable value

Look... Like water is "H2O," chlorine is a formula. It's either chlorine or it isn't. Sure, there may be additives like fillers (so the tablets hold their shape), stabilizers, or colorants, but the formula for the chlorine, itself, is universal. The only differences would be in the integrity of the container, the size of the tablets, the concentration (strength) of chlorine in the tablets, and the cost. For us, the cost of maintaining a pool -- while substantial -- is worth the time, trouble, and expense. We have a simple residential pool, and my husband is a fanatic about keeping it pristine. Since we live in Texas, we're usually out there swimming at least once per day, for a minimum of 5 months out of the year. We used to purchase all our gear and supplies at the local pool company, but then one day I noticed the price tag at Sam's. I started researching and comparing, and found that, even if the chlorine concentrations were the same, the Members Mark tabs were less expensive by far. But then I realized the MM tablets were actually stronger, and I could save even more money by using fewer tablets! No competition. And, other than the membership cost, I get them delivered to my door at no additional expense? There's a substantial benefit!
