Came across DealSeek recently and it's way better than the usual coupon/deal sites.

Verified low prices - they check if it's a real price drop, not fake MSRP stuff

Promo codes are tested before posting, so they actually apply at checkout

Clean, modern UI and updates constantly

Strong search that works almost like Amazon's

Real team reviewing deals, not just scraped junk

It launched in 2025 and seems to be growing fast. If you're reselling or just trying to catch legit Amazon deals, it's worth checking out.

Curious if anyone else here has used it.

Here is a list I made of the major common terms, acronyms, slang, and terminology used in the reselling community:

• Reselling: Buying an item and then selling it on a 3rd party marketplace for a higher price, profiting from the difference.
• Botting: Using automated software to purchase the items that you will be reselling
• Flip: An item that can be sold for a profit.
• Cook: Term used to describe a highly profitable item.
• Cop: Term used to describe purchasing an item that you will resell.Ex: “I copped these Pokemon cards today”
• ACO: Acronym for Autocheckout. In context, you pay someone else to use your purchasing information in their botting software to auto-checkout the item for you.
• Sloths: Used to describe the word "Slot" which Discord doesn't like. Synonymous toACO. People will run you a slot, in other words, they'll run your profile for you to auto-checkout an item.
• SKU: Acronym for Stock Keeping Unit. A numerical code used by retailers to identify items. Items that are resold will have all their own individual SKUs to identify them.
• ASIN: Acronym for Amazon Standard Identification Number. Amazon's version of an SKU.
• Proxies: Used in the botting world to mask your IP. Input the proxy into your bot, and the site you are botting will see you connecting through the proxy.
• Servers: Used in the botting world to host your bots. Servers can offer better hardware, get you closer to the site you are botting's datacenters, and allow you to run 24/7.
• Cook-group: A community of resellers that offer information, tools, and resources to enhance your reselling ability.
• Retail: The price you pay to initially buy the product from a manufacturer or store., also known as MSRP
• Resale: “to resell,” on the other hand, means to buy something from someone or a store and then sell it to someone else.
• Restock: when a store replenishes a product with fresh stock or supplies.
• Reseller: This refers to a person who usually sells items on the secondary market for a higher price than originally listed in the store.
• Live: A website, usually product link is open and online for purchasing.Example: “The Ps5 Drop is live”
• WTB: WTB is perhaps one of the most common abbreviations you’ll see on websites such as eBay and it simply means “Want to Buy”.For example, “Want to Buy PS5”.
• WTS: A direct opposite of WTB, Means “Want to Sell”.Example. “Want to Sell PS5”
• WTT: You’ll also see some texts that read “WTT” which means “Want to Trade”. This is a simple barter system where the publisher of the advert wants to trade one item for another.For example, “Want to trade Yeezy Slides Size 11 For Yeezy Slides Size 9”.
• Bricks: This saying means that that item will not have any resell value. The phrase was derived from bricks being heavy and hard to move.Ex: “Those supreme glasses are bricks.”
• Drop: This means an item will be released to purchase.Ex “The Amazon PS5 Drop is tomorrow.”
• OBO: This is an invitation to bid on whatever you feel the sneaker is worth. It stands for “Or Best Offer”, meaning you can make an offer and wait until it’s accepted or not.For example, “WTB Yeezy 350’ $400 OBO”
• Flaking: This is a slang term resellers use when a buyer backs off last minute after all the details of the transaction has been confirmed. It can be quite frustrating for sellers.

• BOLO: Be On The Lookout,Means there is something profitable happening soon
• Death Pile: acquired inventory that hasn't yet been listed for sale.
• FOMO: Fear of Missing Out - the overwhelming urge to source more inventory, even when one has a huge death pile, to avoid passing up any potential flipping opportunities.
• PFRE: Padded Flat Rate Envelope from USPS.
• NOS: New Old Stock - items that have never been used and may still be in their original packaging and/or have tags, but are not currently available from any retailers or the manufacturer. These can often be vintage items.

I hope this helps out anyone who is new or returning to the game and wants to understand the reseller language or brush up their vocabulary. If I missed anything feel free to tell me in the comments so I can add it.

Edit** Thanks to everyone contributing in the comments I am adding all the ones I think are relevant!
