Hello Miguel!
We appreciate the honest feedback. If you take a look at our shipping info we recommend placing cold shipping orders early in the week. You ordered on a Thursday and your package was not delivered until Monday and likely sat in a warm USPS location over the weekend. For the absolute best results, it's best to order on a Monday or Tuesday.
Cold shipping definitely has its flaws and our current way of shipping items with a cold pack is the most economical and effective way we have found. With extra cold packs comes added weight and larger shipping boxes which increases the overall cost. We have found that in most cases customers would rather pay a cheaper shipping price than pay more than our current prices for cold shipping.
For those customers who don't mind paying extra and would like their package to arrive with cold packs still semi-frozen, we do offer UPS Next Day Air cold shipping.
We will reach out directly as well but thank you again for the honest feedback, this will be considered as we are always working to improve our customers experience.
