Taking cash payments
Cash is still one of the most common ways people pay at car boot sales. Many buyers arrive with notes and coins already set aside for the morning, especially when buying lower-priced items.
Before the event, prepare a float with enough small notes and coins to cover regular sales. Having change ready helps transactions move quickly and reduces awkward situations with buyers waiting around while you search for coins.
A basic float could include:
- £1 and £2 coins
- 50p, 20p and 10p coins
- Several £5 notes
- A few £10 notes
Try to avoid starting the day with only large notes. Even inexpensive items can quickly empty your change supply if several buyers hand over £20 notes in a row.
Keep your money organised rather than loose in pockets or bags. Many sellers separate notes and coins into sections so they can count change quickly without exposing all of their cash at once.
Security also matters. Avoid leaving cash unattended on tables and avoid openly displaying large amounts of money. If possible:
- Keep most notes out of sight
- Carry only working change on you
- Move larger notes into a separate secure place during the day
- Stay aware of distractions around the stall
When giving change, count it out clearly into the buyer’s hand. This helps avoid confusion and gives both sides a chance to confirm the amount before the transaction finishes.

Avoid ‘wrong change scenarios’
Busy car boot sales can become noisy and rushed, especially during peak morning hours. Most payment disagreements happen because neither side clearly confirms what was handed over.
A simple habit can prevent many problems. When a buyer gives you money, say the amount out loud immediately. For example:
- “That’s a ten.”
- “You’ve given me a twenty.”
This makes the transaction clear to both people before the note disappears into your cash tin or pocket. It also helps prevent the common “I gave you a £20” disagreement later.
Take your time with change rather than rushing. Count it out carefully and audibly where possible. If a buyer seems distracted or hurried, it is still worth slowing down enough to confirm the amount.
You do not have to accept every note handed to you. If you genuinely cannot provide change, it is fine to say:
- “Sorry, I can’t take that.”
- “I don’t have enough change for a £20 at the moment.”
Most buyers understand this, particularly early in the day before sellers build up a float from smaller transactions.
It is also sensible to check larger notes before accepting them. Common checks include:
- Feeling the texture of the note
- Looking for holograms and transparent windows
- Checking print quality and raised ink
- Comparing with another note you know is genuine
You do not need to become an expert, but a quick visual check can help you spot obvious problems.
Taking digital payments
Digital payments are becoming more common at car boot sales, particularly for higher-value items where buyers may not carry enough cash.
Offering a digital option can help prevent missed sales when someone wants an item but does not have the right notes or coins. It can also reduce the amount of cash you carry during the day.
Common digital payment options include:
- Bank transfer
- QR code payment links
- Mobile banking apps
- Card reader devices
- Contactless payment systems
Before relying on digital payments, make sure your phone is charged and that you have a reliable mobile signal at the venue. Some fields and rural sites may have weak reception, which can slow payments or cause failed transfers.
It is also worth checking incoming payments properly before handing over expensive items. Wait for confirmation rather than assuming a transfer has completed instantly.
Cash and digital payments both have advantages.
Cash advantages:
- Fast for low-value items
- No signal required
- Easier for quick bundle deals
- Common at traditional boot fairs
Digital payment advantages:
- Useful for larger purchases
- Reduces the need for large floats
- Can prevent lost sales
- Less physical cash to carry
Many sellers now use a mix of both methods. Taking cash keeps smaller sales moving quickly, while digital options give buyers more flexibility if they do not have the right change.
