I have been going through all orders and shipping those I believe may be safe with insulation and ice packs, or being held at the post office for pickup. My weather here was at 100F the past couple of days and looks to drop down to around 90 on Tuesday (today), so I will get more packages out then. Express packages are for sure going out this week as that is typically safe. In this heat, ice packs tend to last about a day, so they will protect packages going out, but 2-4 days in shipping and by the time they reach your state they offer no protection. Please choose express shipping whenever possible. If you are close to Oregon (WA, CA, NV, ID) shipping is usually fine via priority. Again, I have not had many issues shipping anywhere via priority, but I can see it happening more and more with USPS delays and rising temps.
I will be looking into changing to a different carrier after this week so I can offer safer, more reliable choices.
