Before making any such change, you might want to run an enquiry past the Advertising Standards Authority and Trading Standards.
I think you'll find the answer from both the ASA and TS will be that on a venue luike eBid (or any other similar online venue) the offical stance will be - "only if every user abides by the '
previously advertised for 30 days with shipping cost stated, and with no product price inflation when declaring free shipping' rule" otherwise they'll likely say "see you in court".
Also, this is an extremely emotive subject and personally I much prefer the existing declaration of shipping cost included. Please do not turn into a deceit-encouraging organisation like the dark side. You and your members have spent years building eBid as a clean and reliable alternative to American disingenuity, don't throw all that away - please.

p.s. - no need to lie by using the word free - you could create a new listing classification, for example "ONE PRICE" for buy now items - then adorn the site with info banners that trumpets eBid's ONE PRICE listings mean the price you see is the total you pay for product and shipping - no extra charges are tagged on, etc.
Of course, it would need a little coding done - especially for cross border sellers and worldwide shippers - they'd need multiple fields to reflect the different shipping costs to different zones.
Alternatively, turn the entire site ONE PRICE for buy now items - let the sellers continue inputting product and zonal-shipping costs as per now, but auto-combine them per zone of buyer viewing the page or listing. Leave the separate shipping for auction format only and remove the buy now price from auctions .... but then you'll become too much like fleecebay.
