What are your observations on Black Friday?

Black Friday suppose to be the best shopping day of the year but the reserve is the case in JumiaBlackFriday shopping, lots of Nigerian were disappointed on the way jumia conducted the sales, people kept vigil in order to make a purchase but to no avail, the Jumia website was shutdown at about 12:02am on friday leaving many people stranded though the site was up again at about 30 minutes later but then the FlashSale item at that time which is Infinix Hot 2 was out of stock which made people to suspect a foul play.
jumia items were suddenly increased in price, a phone of #24,000 was increased to #29.999 before giving their 55% off, making this item to be on a high side after slashing it with some percentage off.
I myself I bought lots of items on jumia blackfriday but I am still contemplating if I should pay for these items when they arrive or I should shun them, incase you want to know the items they are; (Tecno Camon C5, MI Redmi 2 and HP Laptop).

If you need any of these items declare your interest.
