Glad to be of help. It perfectly fine to ask so many questions :)
My worry is that there are already a number of people selling movies so is it a market worth entering into?
Almost any market is saturated with sellers. One factor that might help you stand out from the rest is how you market your products, your pricing, customer support, shipping - these factors will greatly affect your turn over in your store!
Also, I have tight budget so cannot be spend Â£500+ or so on products. Is this going to be an issue?What about dropshipping? Is this a viable alternative?
Your budget should be fine to help you get started. Usually for sellers with a limited budget, dropshipping is a good option to consider. You can couple actually stocks (from wholesalers) and dropshipped stocks to help provide your customers with more products/choices.
As I live in the UK would it best to buy just films that can be played in the UK?
If UK is your sole market, then yes of course your movies should be compatible with the system being used in the UK, but if you intend to sell to customers from other countries might be best to offer various types of systems to accommodate your customers needs
How do I deal with shipping to other countries? Also does the SaleHoo store covert the pries I show in pounds on my site to dollars etc when foriegn visitors look to buy products?
If you source your products from dropshippers, they will arrange shipping for you. Otherwise you will need to provide shipping for your products, you have various options for SaleHoo Stores and may refer to this tutorial to help you set it.
As for your your currency, you can update it by adding it manually to your admin site. To add GBP, please do the following:
1. Go to Settings > Geographical Settings > Currency
2. Click on the button, you'll find this on the upper right corner of your admin screen
3. Fill in your Currency Title (), Code (), Symbol Left(), Decimal Places(2), Value (refer to Link hidden: Login to view for current rate) and Status (Enabled).
4. Click Save.
5. Go to Store Settings > Configuration
6. Scroll down to Local > Currency and select Great Britain Pounds to make GBP as the default currency for your store.
I already have a eBay site (no shop). Can I use this in conjunction with my site.
It would be a good way to divert traffic from eBay to your SaleHoo Stores and vice versa. You can add your eBay links in your product descriptions or mention your eBay business in your SaleHoo Store's About Us page.
Hope I have addressed your concerns adequately :) Should you require any further assistance please feel free to let us know!
