Father’s Day sales are in full swing at most of the DNA testing companies. Prices are summarized here: http://thednageek.com/dna-tests/
The next big sales probably won’t be until November.
Special note for Y-DNA upgrades at FTDNA: Log into the relevant account to see pricing. Each upgrade combination (e.g., from Y-12 to Y-37, from Y-111 to Big Y 500) has it’s own price. If you are unsure whether you’re getting the sale price, call FTDNA’s excellent customer service to ask.
And as always, please consider submitting your lab processing times to the ongoing survey.
