I have faced this problem myself and here are some tips that can help. First of all, I recommend carefully checking the reputation of the store. Read reviews from other customers on independent forums and specialized sites. Pay attention to the overall rating, as well as specific comments about the quality of the product and the speed of delivery. The next step is to check the legitimacy of the store. Make sure that they have valid licenses and certificates confirming the quality of their products. Reliable stores usually provide this information on their website.
