The internet is full of random stores that look legit, but then I look on TrustPilot and they turn out to be scammy or unreliable. Is there any UK store (online or in person) where I can buy home treadmill (looking for something simple, nothing like the fancy ones in the gym with big incline, more like under-the-desk but with a handrail, preferably removable) and preferably to pay in installments, like Klarna? Amazon seems to be the most fitting option right now, but they're pretty much also filled with unreliable resellers, so it's still a gamble.
