hi, welcome
i have a law degree and have the experience to answer your question
yes, you ought to incorporate...although...incorporation helps more with financing, tax, suppliers, hiring employees, succession and exits...as far as negligence and product liability goes, however, the corporate veil is about as useful as exclusion/indemnity clauses i.e. not very
the only reasonable defense against product liability claims for retailers is documented quality control, supplier benchmarking, warning labels, money for lawyers, insurance and plenty of good luck
overall, look...the tort of negligence is very complex....so for all intensive purposes, yes, incorporate and put the damn stickers on, but does that alone discharge your duty of care under all circumstances and indemnifies your venture against all possible future negligence claims? not by a long shot. the only way to achieve that sort of outcome is to mothball the whole project from the beginning. oh the irony
