The cost of a rental cooler was too much. So we purchased our own water cooler and returned (While they were still Zephyrhills), then Ready Refresh has constantly increased their costs for delivery and bottled water (sigh). Recently they increased the cost of each bottle by $1, which adds up quickly. NOW they are asking us of we want to "Tip our Driver", What? You aren't paying your drivers enough and we have to make up for that?Don'tDon User's recommendation: Do not waste your time. Get a water filter and attach it to your sink. Replace the filter every 30 days. It's less of a headache and much less $$$.
