Value of Sweatcoins


So far I have not seen where I can get any value from my acquired and earned Sweatcoins. Will That change?
For example - Harrys offer I currently see. Costs me 9.99 sweatcoings PLUS $3 shipping. But if I go to Harry’s website I can get the same free offer & free shipping as well.
So what VALUE am i getting for my coins? I have seen no offer where I can actually spend coins. All of them are for an OFFER where I pay money in addition and can find the same offer or better elsewhere with a quick internet search.
Do you understand my frustration and the strong impression that there is no value to the coins I am earning?
