I called to check he'd posted some of dds clothes I ebayd on the way to work yesterday, which he did and he texted 'the postage is £2.85'. I didn't reply but when he's left the post office recipt carefully placed on my bedside table before he went to work!
It's not as if I'm spending the sale on myself. It'll go on more clothes for dd.
Would I be unreasonable to find the grubby old tin full of pennies we take on holiday for the arcade games and leave £2.85 exactly in pennies on his bedside table? 
Yes petty and yes lighthearted but it's fucked me off!
