Buy sweet or hot paprika in sealed tins; Tokaji is a sweet wine, so look for the grape juice or apricot jams if you avoid alcohol.
Ask who made a piece and where. Check materials and shipping. Bargain politely only where invited; respect fixed prices in boutiques and artisan shops. At the Christmas markets, prices are fixed and higher than in shops; the Great Market Hall is better value for paprika and souvenirs.
