Sea Foam seems to be a little more expensive lately. It used to dip below $7 every now and then on Amazon, but that hasn't happened in a while.
Fortunately, it's still inexpensive on some other sites. If you need to restock, here are some current online prices for a 16-ounce can of Sea Foam:
$6.97 ..... Walmart
$6.98 ..... Menards
$7.99 ..... Napa Auto Parts
$8.99 ..... Advance Auto Parts
$8.99 ..... Amazon
$11.99 ..... Autozone
