Says in store... Did you go? Prices, are usually different online, compared to in store sales.

I go weeks with riding my bike sometimes. This tender is a must. Does a great job keeping the battery strong and ready to go. The status light is very convenient.

If you don't need one that is weather resistant, I use this one and like it. Far cheaper:

I used it "outside" (inside non-insulated garage) all summer in the Arizona heat with no issues.

Another non-weather resistant sale option is Harbor Freight's January Parking Lot Sale. 30% off jump starters and automotive battery chargers.

The VIKING 4 Amp Fully Automatic Microprocessor-Controlled Battery Charger/Maintainer will be $40 - 30% = $28
