Unfortunately, at this point I think its safe to assume that this is not just a misunderstanding considering:

• The number of people having issues (looks like it could be 9 or more)
• The same module being sold to at least two people (both of whom paid) with no indication in the ad of multiples being in stock

Others may have a different view, but my thinking is that anyone still waiting to hear back from sugarfreedaddy who used PayPal goods and servcies should consider opening a dispute and immediately escalating to a claim. Anyone who paid with F&F should see if they can initate a chargeback with their bank or credit card company.
