I want to publish an extended database with products on my WordPress website. It will have a lot of custom fields. Most of the productdata is collected by hand, since the productfeeds of the webshops aren't very complete. I want to put all the data in a Google spreadsheet, so my co-worker and I can change the data anytime and anywhere.
1) I would like to import that spreadsheet as the first (leading) feed in PT. But: my own database doesn't have any prices. Is that a problem?
2) After that, we will import some affiliate feeds. I'm al little worried that our own data will be overwritten. Is our data safe? (I'm pretty sure this is a pretty stupid question..)
