storage on a budget

[mia]

I'm an amatuer wine drinker with an affinity for red wines. I love to have them on hand just in case friends pop over but I have a storage problem. I'm single lady who lives in a small apartment, in a hot very a climate and on a budget, so I can 't invest in a cooler right now. Because there is always opened wine leftover from my small get togethers as well as friends constantly bringing several bottles as gifts, they're inevitably ruined because of the heat. Short of telling my friends to forgo their wonderful gifts, is there anything I can do?
