K’Nex Connectors: £1 (+ £1 p&p), Twice
Ted needs to stock up his supply of K’Nex following the construction of his K’Nex Fruit Machine, K’Nex Ball Amusement Machine and K’Nex Binary Machine, and so when he saw these really cheap connectors on eBay, he jumped (but not fast enough – some had already been sold).
He paid £2 for 70 eight-way white connectors, and £2 for 70 seven-way blue ones, including postage. He bought them only two or three minutes apart.
Two days later, Ted received them – as two parcels! What is more, they cost £2.60 each to post!
The seller paid 40p to eBay to list the items, but this will be ignored because there were about eight items in the one listing.
Each item incurred eBay commission of 10% of the sale price, i.e. 10p.
Each item incurred PayPal commission of 3.4% + 20p = 27p.
So the seller paid a total of 2 x (10p + 27p) + 2 x £2.60 = £5.94 and received £4!
What is more, there were a total of 36 rubber bands around the pieces, when two would have been adequate!
