About
Built by a seller who sources every day.
I'm Simon Knight — a UK-based Amazon FBA reseller and the person behind FBAMogul, OA Hero, SellerOracle and KeepaVault.
I run FBAMogul — a YouTube channel, a Discord community, and a mentoring programme for Amazon sellers. It's where I share the sourcing strategies, workflows, and mistakes that shape how I source on Amazon every day. The community that's grown around it is why I'm building software at all.
Why OA Hero exists
Every online-arbitrage seller learns the hard way that product pages don't tell you the truth about what you're allowed to sell. Amazon won't tell you a brand is IP-protected until after you've bought stock. Retailers don't advertise their "no resellers" policy until you've placed the order. OA Hero exists to flag those problems before you spend the money.
On Amazon and Qogita product pages, OA Hero shows brand restrictions, ungating checks and a barcode lookup. On over 600 UK sourcing sites, it shows whether the shop allows resellers, its order limits, its VAT invoices and its customer service contact.

OA Hero is built by Simon Knight, also known online as FBAMogul. Simon has sold on Amazon since 2022, and each feature in OA Hero is there because it saved him from a mistake while sourcing.
The Offers tab in OA Hero has partner links. FBAMogul may earn from them, at no cost to you.
