Fastbay offers several options to reduce the number of products to be sent to the marketplace.
Although you can not manually select the individual products to send to eBay (module groups synchronizabile products by category), you can get the same effect by disabling the products you do not want to send.
This can be done through the Fastbay editor in product sheet (see the relevant section of the documentation) by setting “disable synchronization” to “YES” for products you want to skip.
(note that any previously synchronized product being sent as disabled, will be closed at the subsequent synchronization).
Another chache to reduce the total number of products sent on eBay is to use the “maximum quantity” filter in the first module configurations screen.
By setting the maximum amount to 1, combined with the option “Use this value for products that exceed this quantity”,
module will send everything with quantity “1”, drastically reducing the total volume of your sale (in units and amount).
Remember that the module has no way of sending or updating products if the limitation comes from eBay !
