I went on signature solars webpage yesterday ready to buy an eg4 12k hybrid mini split. When I added the item to my cart and looked at final pricing with shipping I was quoted a shipping rate of 36ish bucks from FedEx. However once I proceeded to check out that shipping option was no longer available and I was left with 400-600 dollars in shipping options only. IMO this is very deceptive and could be easily fixed by not offering that shipping option on the cart page. Thankfully I noticed the swap at check out before I made the purchase. I contacted sales at signature solar and was told that the FedEx option is known to them to not be available for this item and they would not honor the price listed in the cart essentially. They also refused to match another online competitors price that included free shipping. I would avoid this company given what I again call deceptive business practices for offering one price and not honoring it.
