As an FYI, Ocean Odd Lot in Shrewsberry, New Jersey will be closing for next season. There are rumors that they are looking for a new location, but at this point nothing is confirmed. They sell the 12.5% for $2.99 a gallon or by the case of 4. The South Plainfield store will remain open. I even took a step further and spoke to the manufacturer and even to deliver a pallet, the price would be like $3.50, and the reason is that Odd Lot ships there own Liquid Shock.
Walmart has been funny with stock and prices over the last year. I even believe the 8.25% is now 6%, but not 100% certain.
