what I meant more specifically, is options that must be selected on buy it now items, as auctions are usually just one item, and it is a predefined item or items, whereas with buy it now items, the seller has the same item in different colours or styles or sizes, or shapes, or can come with optional adapters and etc, so you would have to select the options before you click the "buy now" button on the main item page. Similar to the way eBay works, so you can have options on buy it now listings with multiple items on which you have to select the option before you press buy now, but proper auctions have no options as they are a set predefined item, that you cannot change, and there will only be one person winning the one item or group of items from the one auction, whereas the buy it now auctions can have multiple items/sets of items and can have multiple winners, but require options for things like colours and sizes, whereas a proper auction would have the colour and size in the title or the description. As for passing the option info through the payment gateway, this is unnecessary as this information only needs to be forwarded to the seller. If you added a way that the seller can see each of their orders from buy it now auctions with multiple items, then each order could have all necessary information like: name, address & postcode, contact numbers, and all the options that have been selected. Then they can use BF auction sites to track their orders as well, leaving paypal as just a payment gateway, and keeping people using your extension and our site, not to mention that it will build more interest in your extension and our website. But in any case I am sure that it would be easier to get the info from options for colour, size, etc... directly to the seller rather than through to the payment gateway (PayPal).If you cannot have orders managed through BF auction then maybe an automatic order email sent to the sellers email address that they must include somehow?
Thank you for your time, patience and help,
