hi everyone

i would like your opinions on this situation...
i have recently purchased the chanel bag on ebay. i won the auction for $1025. its been almost a month and still hasnt gotten the bag due a mix up. lol i had received instead a book from the seller and had to return it and she sent me a bag fianlly and its probably going to be here tomorrow or sat.. hopefully. shes been very responsive and i am crossing my finger that she sent me a right item this time and the bag will be authentic. sigh.. i never had to wait this long for an item purchsed within US. but ive been wanting the bag for some time and thought it was worth waiting and shes been really responsive so I wasnt upset or anything about delayed shipping...
BUT!!! I found out seller is shill bidding!! I didnt notice at first but my sister noticed and told me to take a look!!! I am 99.9% sure she is shill bidding... she has other two ids that are being used to bid on her items..
I took a look at all of her current and recently sold items... every one of her item has these two ids making bids.. and those two ids made bids on the bag i won too... in fact, one of those bidder is the only bidder that bid agaisnt me from $800 and up. sigh...
What confirmed that she was shill bidding is that one of those bidders actually ended up being a high bidder in auction for a burberry scarf.. the bidder who had 0 feedback before left her a feedback for the item ONE day after the auction ended lol.. and she left the bidder a feedback right after and she relisted the item right after lol!!
and again that same id is back to bidding on her other items..........
I am waiting on the bag but now i know shes shill bidding, i am upset... Do i think the bags still a good deal? yes.. but just the thought of me anxiously bidding on the item while in truth its the seller bidding on her item to raise the price makes me really sad and upset

and truthfully, I do feel cheated out of money... now i am very torn.. should I report this to ebay and have ebay cancel the transaction? but she's been very nice and i donno if I really should report her...but then again, she will be doing this over and over again if I dont report her... or should I just confront the seller myself and return the bag for refund??? ahhhh!!!
what should I do????
