I haven't got a list (yet). But if you don't know what to suggest, how about:
--perishables like nice food and drink. Maybe a grade above what you normally buy for yourself (posh olive oil, chutneys, wine etc)
-- a replacement item for a luxury or practical item that is wearing out (e.g. slippers, PJs, cashmere jumper, scarf)
-- an upgrade for an everyday item that you use all the time (e.g. good quality pans or kitchen knives to replace cheap ones)
-- a charity gift for a third-world or homelessness charity, or a local charity that is close to your heart
-- book tokens or Amazon vouchers so you can choose yourself
-- voucher for something you like doing (cinema, manicure, luxury afternoon tea for two, anything really)
-- if you're really fussy and don't like change then ask for supplies of your favourite perishable product (ask them to buy you a particular brand of chocolate, biscuits, shower gel, lipstick etc that you usually buy for yourself)
