Get one of those reacher-grabber things they promot to the elderly; that’ll let you access more of the space (you can use the grabber as a pusher as well).
Then store lightweight things that you’d like somewhat accessible and are aggravating to store somewhere else. If this was my mom’s space (she loves to travel), she’d store her empty luggage in there. If this was my sister’s, she’d put all her holiday stuff into plastic bins with large handles and store that in there.









Whatever you spend it on, may I make a suggestion, if you have a little extra money yourself? Spend the gift card money, yes: buy something you’ll enjoy, share that joy with the people who got it for you, let them see how happy they’ve made you.
Then take the card that the giftcard came in, put in $75 cash, and put it in a special place. Do that every time someone gives you money or a giftcard. As I’ve gotten older, a lot of the people in my life have died, gotten ill, or moved away. Sometimes, when I’m feeling sad or depressed, I’ll go to my little drawer of cards and pull one out at random. I’ll re-read the message, and think about the person and the love that we shared at that time, and I’ll take the money and do something special for myself, to cheer myself up a bit.
Then sometime in the next few days, I’ll get the same amount of cash from the bank, put it in the envelope, and replace it in my stash: the caring we felt for each other at that time was true (regardless of how things eventually turned out), so the cards give me a little emotional boost and the cash lets me do something for myself that I’d normally not spend money on. It helps me feel better, even if only for a little time.
[I’ll also be honest and say that sometimes I’ve run out of money, and something will twinge and I’ll remember I have this little stash of cash, and having that has helped me get through some slightly tough times. But I always put the money back in the cards when I can afford it.]
