FAQ
Frequently asked questions
What is FlipFlop?
FlipFlop is a Chrome extension that automatically identifies products on Facebook Marketplace listings and compares their prices across major online retailers like Amazon, Walmart, and eBay.
How do credits work?
Each credit lets you look up one product. When you view a Facebook Marketplace listing, FlipFlop uses one credit to identify the product and fetch comparison prices. You can buy credits in packs of 50, 150, or 500.
Do I need a subscription?
No. FlipFlop uses a simple pay-as-you-go model. Buy credits when you need them, and they never expire.
Which retailers do you compare against?
We compare against Amazon, Walmart, eBay, Best Buy, Target, and other major online retailers depending on the product category.
Is my data safe?
Yes. We only process listings you view on Facebook Marketplace. We don't track your browsing history, sell your data, or store your Facebook credentials.
Can I get a refund?
Unused credits are non-refundable, but they never expire. If you experience a technical issue that consumed credits incorrectly, contact our support team and we'll make it right.
