Outdoor gear compresses, which makes it cheaper to send than it looks. One item in the category cannot be sent at all.
Fuel does not post
Gas canisters and liquid fuel are restricted and most couriers refuse them outright. Sell the stove, say clearly that fuel is not included, and offer collection if a buyer wants both. Packing outdoor gear.
What decides the rest
Volume, reduced by compression. Stuff sacks and compression straps are what make this category cheap to post, so use them — but never compress anything that was damp, and tell the buyer to store a sleeping bag uncompressed when it arrives.
Poles and anything long can attract a length surcharge. Check before quoting.
The four options
Courier for most gear, compressed. Your own delivery locally. Pickup for large tents, bulky packs and anything with fuel involved. Buyer arranges occasionally.
When collection is the honest answer
For big family tents, for fuel-adjacent sales, and for anything where volume makes the parcel absurd. Agreed before bidding with a collect-by window of 72 hours unless you set otherwise. How pickup works.
Combining wins
Gear combines well — several items compress into one parcel. Combining is on by default and you set what each later win adds.
The thing that must happen before any of this
Dry it completely. A parcel sealed with damp fabric inside arrives smelling of mould, and mould does not come out. That is a packing rule, and it is also the most common reason a delivery in this category ends in a return.
Questions people ask
Can I post a stove?
The stove yes, the fuel no.
Should a sleeping bag ship compressed?
For the journey yes, with a note telling the buyer to store it loose.
What about optics?
The fragile exception — cased, bubbled, boxed.
