Nice @egginc.org! I hope so you'll do great with that venture. I am from Philippines too and I think the price fluctuation becomes a factor in determining the value of the product or the amount of Steem/Sbd to be paid in an order.

Since SBD is a broken peg, I suggest to have around 3-8% value reduction as you may face a sudden price down and the transaction fees.

Looking forward to see it.
