how to advertise my online website?

I don't know if I can post it on here, but I just set up my own e-commerce business. I'm 15 and yeah I know it's a little weird but I guess creating is a passion of mine.
How can I advertise it? I used to have a really successful etsy but I wanted to move onto something else. Would it be wrong to put up flyers or something in my neighborhood? I purchased a blog ad but i dont know. Anyone have any ideas? Thanks!

It's kind if a small scale waste of time to promote locally with flyers, when the right online promotion cab attract hundreds of visitors a day. (Of course if you were promoting a local service the flyers might e the best way to go.)

It's easy to loose lots of money on Adwords if you don't have an optimized sales page with known conversions rates, way you has a quite respectable 2% conversion rate, ad clicks costing $0.50 to $3.00 each would end up costing you $25 to $150 per sale.

Google was promoting this first time user voucher page a while ago, if your lucky perhaps it can still finance your advertising experiments.
