The initial public offering of Letsbuyit.com, the pan-European e-tailer due to list in Frankfurt tomorrow, was hanging in the balance yesterday as one of the four banks handling the issue said it had pulled out. Bids for Letsbuyit.com shares ranged between €5.50 and €5.80 in "grey" market trading yesterday. This compared with the €6-€7 originally announced and a far cry from the €15 it said it could achieve before shelving its initial listing.
