Apple specifically precludes anything that can't be delivered via the app from using in-app purchases. So you're free to tie a credit-card to services and real-world fees (think Uber) without paying Apple any transaction fees. Here's Apple's documentation on what they support (and don't allow) for in-app purchases. https://developer.apple.com/in-app-purchase/In-App-Purchase-Guidelines.pdf Happy to help in any way I can.

Hone decor / furniture industry is one of the highest profit promising industry today. The profit margins on home decor ranges from 20% - 45% depend on the price of the product. If you're looking to get quickly popular, I suggest you start with the online store and promote it on offline as well. Keep the margins low initially so that you can attract more buyers. As the business grows, reinvest the amount back on the business so that you can stock more varieties. All the very best.

I'd ask Rocco Baldassarre. He is the best online marketing consultant I've ever seen and can surely give you concrete advice. Said that, my advice would be a) your own e-commerce store so you can drive traffic to it without losing money on commissions b) learn from best selling products (you can see sales ranks of competing products if you register as an amazon affiliate marketer; it's free) and copy their structure, split test regularly Hope it helps!

There is quite a bit of information available online about eCommerce conversions rates. According to a ton of sources, average visitor-to-sale conversion rates vary from 1-3%. This does not mean the Furniture conversions will be the same. The bigger problem is that visitor-to-sale conversions are not a good data point to use to measure or tune your eCommerce business. All business have some unique friction factors that will affect your final conversion rate. It's very important to understand each of these factors and how to overcome them. The best way to measure and optimize is to take a conversion funnel approach. Once you have defined your funnel you can optimize each conversion rate to better the total effect. For example: Top of the funnel: - All web site visitors, 100,000 / month First conversion: View a product page, 50% of all visitors Second Conversion: Add to Cart, 10% of people who view products Final Conversion: Complete Checkout, 80% of people who put items in a cart In this example we see that only 10% of people who actually view products put them in to a cart, but 80% of those people purchase. If you can figure out why visitors are not adding items to their cart and fix the issue to increase the conversion rate, revenue should increase significantly because of the high checkout rate. You can use free tools like Google Analytics to give you a wealth of information about your site visitor and their behavior or there are some great paid tools as well.
