One thought. A local , small, Carphone place has a very nice manager who is very keen on sales. Once, when I was deliberating on a purchase she offered a phone for me to try out for a day. (It was about 20 months ago when I was thinking of buying no 2 daughter a Galaxy 1).
Maybe they have the odd phone or two lying around that they can offer on this basis? (Presumably to older clients with credit cards, and not chavs??)
The reviews of Y are mixed, but the Y does meet your original spec - tis a simple smartphone. IMHO, the Tocca is very much an antique now.
