When making an offer on eBay items please make sure you make a realistic one.
Many Categories only allow one offer to be made, so if you go in with an offer that is too low, then it will be declined.
Ebay has now updated their systems & when the Seller receives a best offer they can not see the full name of the Buyers ID. Therefore, as a seller we are not able to say 'We are not able to accept the offer of £6.50 but we are willing to accept £7.50' etc.
Another thing you will need to note is that if you want 2 of an item & the Buy it Now is £8.99 DO NOT put an offer for £15.00 & then in the notes section write this is for 2 items, as eBay does not recognise this & will charge you £15.00 for each item - even though it is higher than the advertised selling price.
Always pre-check the postage price & the Sellers Terms & Conditions.
