Old enough to know better
I just checked and it looks like the price for super saver shipping was increased to 35 recently. So if the order is over 35 and all items are eligible for super saver shipping, then it's free.
With Amazon Prime (they are raising the membership fee to $99 this year) shipping is always free, no matter the amount. Plus you get free access to the Kindle library, discounts from other sellers associated with Amazon. If you break down what you need to buy this year (not just reptile stuff, but other things like linens, appliances, tools, computers, audio, etc.) you can see how much the Prime membership saves you.
