Can a seller block you even with a perfect buyer record?

[nickspurs28]

I am sure a seller has blocked me. I have a perfect buyer record and I made an offer to a seller, they did not accept but upon bidding it does not go through. This happened with another item from the same selller.

Can I be blocked by a seller?

As has already been mentioned, sellers can block buyers for any reason they like.  However, it's also possible that the seller listed the item using eBay's standard selling template, instead of using the Advanced Selling Template. The standard template automatically includes the Best Offer option, which would be annoying to sellers who were not willing to sell the item for anything less than the full asking price, as they would not want to receive such offers. If that is indeed the case then if the seller had set the listing up using the Advanced Selling Template he/she could have manually deactivated the Best Offer option, leaving buyers with the Buy It Now price as the only option with which to purchase the item.

Unfortunately given the fact that this seller has now added your User ID to his/her Blocked Bidders List you will just have to accept that you are not going to be able to purchase anything from this seller.  The best option, therefore, would be to forget about this seller and see if you can find an identical item being offered for sale by a different seller who has not blocked you for some reason.
