Local eggs and honestly box - exact change?

local farm puts eggs out for sale and has an honesty box. Eggs are £1.70. We mostly use card/cashless and so sometimes have exact change but often only have £5 note or £1 or £2 coins.

do you think you should only buy with exact change? Is it acceptable to put £2 in and then pay slightly less next time? Put £5 in and take next one free and put in 10p next time?

I assume they don’t want wastage but also don’t want to be short changed! What do you think is reasonable?

If the eggs are boxed up it's likely someone will end up short if she does that.

Just pay, overpay, or don't take them. It's a simple arrangement, and if people want more complex solutions there are shops they can go to.

Just leave £2. That's still cheap for fresh eggs.
