Individual sellers on Amazon can set whatever price they want. Especially for thing that are in high demand.Recently I purchased an Orbit manual water timer from my local Fleet store. I paid $6.48 for the unit at the store. I took it home and before I used it, I did a quick price check on Amazon to see if my local store was close to the Amazon price.
You might not believe this, but I found the exact same Orbit model number selling on Amazon for $149.00 and another place listed at $129.00! I showed Dear Wife the product listing and she could not believe it, either. I have no idea why online these units were selling for so much, but the next day I went back to my Fleet store and bought the remaining 2 units they had on the shelf. For less than $20 at my local Fleet store, I purchased about $450 worth of water timers listed on Amazon!
