Fi builds the Fi Series smart GPS dog collar, a tracker that follows your dog's location, activity, sleep, and escape attempts through a companion app. It is a device-plus-subscription product rather than a one-time purchase, so the way you save here looks different from a typical retailer. The collar itself is hardware, but the tracking features that make it useful depend on an active Fi membership, and that membership is where most of the pricing decisions happen. Fi offers a monthly option starting from $19/month for shoppers who want flexibility, but the real savings live in the prepaid plans: a 1-Year Prepaid Plan at $189 and a 2-Year Prepaid Plan at $339, which Fi flags as its best value because committing longer lowers the effective monthly cost. First-time buyers can also start with a 1-month free trial that comes with a Fi device, which lets you test the escape alerts and activity tracking before locking into a longer term. There is a referral path too, worth $20 off the collar plus a free membership month when someone shares their link with you. Fi is best for owners of active or escape-prone dogs, multi-dog households, and anyone who wants data on how much their dog actually moves and sleeps. Because it backs purchases with a 30-day satisfaction guarantee, the risk of trying it is limited. The brand rewards planning ahead: if you already know you want long-term tracking, the multi-year prepaid tiers are what bring the price down. The codes and deals above are sourced from Fi's own site and verified before listing.
Start by buying a Fi Series collar, then open the Fi app to activate a membership, which is what actually turns on GPS tracking, activity monitoring, and escape alerts. New buyers should choose the 1-month free trial first so they can try the device before paying for a full term. When you are ready to commit, pick a plan inside the app: monthly from $19, the 1-Year Prepaid at $189, or the 2-Year Prepaid at $339 for the lowest effective monthly rate. Keep in mind a one-time $20 activation fee applies when you set the collar up. If a friend already owns Fi, ask for their referral link before you buy so you get $20 off the collar plus a free membership month. There is no promo-code box in the usual retail sense here; your savings come from the plan length you select and any referral credit applied to your account. The 30-day satisfaction guarantee gives you a window to return if it is not the right fit.
Shipping options and costs are shown at the Fi checkout; many orders qualify for free standard delivery above a minimum spend.
Returns follow the Fi policy — check their site for the current window and conditions.
