I'm not shopping today, just trying to understand the spread before I refill. I keep a tiny Notes app list of out-of-pocket costs, and last month two quotes for what looked like the same-size vial landed $23 apart once shipping was added.
One included a cold pack; the other was vague about handling. My gut says the cheapest isn't automatically the answer, but I also don't want to overpay out of fear.
For those of you who've compared options, what actually helps you decide: shipping, paperwork, communication, or just a price you can live with? I'm asking for your own experience, not recommendations for a specific shop.
