When you
The csv export allows modifying product details but is not as effective as it can be, and has one bug that I found. I'd suggest exporting only the fields that you are interested in and that rather than having one very long row,
On export page click + button to expand custom fields selection. But I am agree not all possible field can be selected. See screen 1
By the way you can remove almost all unwanted fields (not all) from CSV file
the export breaks each product into blocks so it can be edited and added to more easily.
What do you mean blocks?
I've noticed that if you change the special pricing, it just adds it to the specials and doesn't replace what's there when imported back.
It is work for me. Try to import again and after import
clear AbanteCart cache in Admin-System-Cache
When you use the selectbox option with more than a few line items, and then save the pricing changes to zero about 50% of the time! You have to reenter the numbers and save repeatedly until it saves properly.
Did you wait for 'Success: You have modified product option.' message? I can not replicate this issue. Please provide screenshot
The sort column shows unusual characters that MUST be replaced manually by numbers. Perhaps changing to an automatic 1 3 5 7... and son on allows for quick sort numbers.
Sort column show 'NA' character only if you did not assign any value for the first added option value. Try to assign 1 and see that next option value added will be 2. Also you dont need to remove 'NA' characters, after save Sort Order will be '0' in this case. Anyway we will improve this small issue.

I'd like to see "Too low to show" instead of sale, so -
You have to "order" to see the price in the cart
or, you have to email vendor to get pricing.
For now we have few features might help you:
Global setting
Login Display Prices: Show/Hide prices if customer is not logged in. Each product have setting
Block Product From Ordering: This will put product to display mode only with no ability to order. Contact us for order message will be displayed.
Many companies have policies that block discounting below certain levels. This deals with that problem.
When you add special price or quantity discount for different Customer Groups this extension give you some space for loyalty
http://marketplace.abantecart.com/customer-experience/customer-group-update-customer-loyaltyA missing feature is to have a text box above, or to the left of an option box providing extensive details if necessary. You can add a text area, but it often creates a scroll down bar. Perhaps a user selectable size option is best?
An attractive free shipping icon (for selected products) would be a good feature.
More later.
Thank you for suggestions.
